The Jamacha Valley lies nestled in the foothills to the east of San Diego at the base of San Miguel Mountain.1 During the Mexican Period the valley was part of Rancho Jamacha, a Mexican land grant consisting of two square leagues, owned by Doña Apolinaria Lorenzana.2 Following the American conquest of California, Doña Apolinaria lost the rancho to the invading Americans.

The manner by which she lost control of her property has often perplexed historians. Following the Mexican War, many California rancheros lost their land to American squatters and land speculators as a result of the Land Act of 1851. Unfamiliar with American legal procedures and forced to mortgage their ranchos in order to cover court costs, most Mexican Californians lost their property while waiting for final confirmation of their claims. It has been contended by many historians, however, that Doña Apolinaria did not lose Rancho Jamacha as a result of the Land Act of 1851, but that the land was taken from her through illegal means.3 This belief seems to have been based on a statement by historian, Hubert Howe Bancroft, who wrote that she lost the ranch through “some legal hocus-pocus that the old woman never understood.”4

Although it may never be known if Doña Apolinaria Lorenzana understood the process by which she lost all rights to Rancho Jamacha, she was, in fact, typical of many Mexican rancheros who lost their property as a consequence of the Land Act of 1851. The transfer of ownership was legal and a consequence of her own action.

In order to better understand the events that led to Lorenzana’s loss of Jamacha, it seems appropriate to discuss the rancho’s history previous to 1850. Before it was granted to Doña Apolinaria, the Jamacha Valley had been part of the lands belonging to Mission San Diego de Alcalá. Prior to this the Kumeyaay or Diegueno Indians had inhabited the valley and surrounding region. Traditionally hunters and gatherers, their occupation of an area tended to be seasonal, with bands moving throughout a specific territory in order to exploit major food resources.5 The founding of the mission and presidio of San Diego in 1769, however, drastically changed the lifestyle and culture of the area’s native population. Although the Spanish established missions in California in order to “civilize” the Indians, their efforts resulted in the destruction of the very people they intended to save.6

The first historical record of missionary contact with the native inhabitants of the Jamacha Valley was in October, 1775, when Padres Jayme, Fuster, Lasuen, and Amarrion baptized the natives of the Rancheria San Jacome de la Marca, or Jamacha.7 Part of the population, however, did not readily accept its new-found salvation. The following month a combined force of natives from nineteen different rancherias, including Jamacha, attacked Mission San Diego, killing Father Jayme, a blacksmith, and a carpenter. One of the warriors from Jamacha, a baptized Christian known as Chilcacop, participated in the murder of Father Jayme.8

Instead of discouraging the missionaries, the attack reinforced their determination.9 The Spanish soon regained control, and conversion of the natives continued. By 1809, fifty-one members of the rancheria at Jamacha had been baptized.10 As the mission prospered, the valley was used to graze herds of sheep and horses, which numbered over 16,000 by 1830.11

Even though the California missions enjoyed several decades of prosperity, the missionaries ultimately destroyed the California Indians. They subjected the natives to unaccustomed labor, unsanitary living conditions, exposure to disease, and a disruption of family ties, social relationships, and cultural values. This resulted in the physical and moral decline of the aboriginal population.12 At their peak, the twenty-one California missions controlled approximately 30,000 Indians.13 By 1834,. the year before secularization took the institutions away from the missionaries, only 15,000 natives remained.14 At San Diego, the death rate amounted to half the number of baptisms between 1769 and 1800, and constituted seventy-seven percent of the number of baptisms and thirty-five percent of the aboriginal population by 1820.15 Disease, a low birth rate, and an inability to adapt to an alien culture were destroying the California Indians.16 The native population of the Jamacha Valley suffered the same fate as did their aboriginal brethren throughout the state who had come under mission control. Although the rancheria is mentioned in a report of 1827, it is doubtful that more than a few individuals remained in the valley in 1835 when the San Diego Mission was secularized.17

Secularization of Mission San Diego resulted in the conversion of the Jamacha Valley into a privately owned rancho. Following secularization, former mission lands throughout California became the property of a small aristocratic class of rancheros. The chief economic activity during this period consisted of exporting hides and tallow. The California ranchero put little effort into improving his surroundings, allowing his cattle and horses to roam freely over the open range, feeding and reproducing naturally. Agriculture amounted to planting only enough food for the small population. Grain or other produce for export or livestock feed was not grown, and manufacturing was almost nonexistent.18

The Jamacha Valley became like many other ranchos of the period. It differed, however, in some ways, from the average Mexican cattle ranch. The average rancho was owned by a member of the rancho aristocracy who had gained his land by opposing the missionaries and advocating secularization.19 Rancho Jamacha, on the other hand, had been granted by the missionaries at San Diego to Doña Apolinaria, a single, pious woman devoted to the church.

The missionaries granted Jamacha in reaction to the threat of secularization, which they saw as an attempt by the aristocracy to gain control of the church’s wealth. In preparation for the inevitable, measures were undertaken in the early 1830s to preserve what could be saved of the mission’s property and to convert the remainder into cash. The priests at several missions ceased to care for the buildings and began to slaughter the vast herds of cattle for their hides and tallow.20 The missionaries of San Diego, therefore, granted a large portion of the mission’s grazing land to Doña Apolinaria, who had long been a devoted friend and servant of the mission. The lands consisted of three separate grants: San Juan de Las Secuas, San Juan de Los Coches, and San Jacome de la Marca or Jamacha.21

Born in Mexico, Apolinaria Lorenzana had been sent with her mother and several other families to California about the year 1800.22 Her mother remarried and returned to Mexico, where she later died. Apolinaria, left in the care of Captain Raymundo Carrillo and his family of Monterey, moved to San Diego at the age of twelve, where the captain had been transferred. Soon after her arrival, the young girl fell ill and became a patient of the missionaries. Upon her recovery, the fathers made her a nurse in the mission hospital. Apolinaria became devoted to the priests and the church. She remained at the mission and never married, teaching the Indians to sew, and caring for the sick.23 As a result of her religious devotion, the people of San Diego nicknamed Apolinaria “La Beata,” meaning “the pious one.”24

Doña Apolinaria first occupied the Jamacha Valley in 1831.25 In 1833, the missionaries gave her the necessary certificates and she applied to the government for ownership. In 1840, she received a grant for two square leagues of land which, according to her diseño, lay entirely within the Jamacha Valley.26 Meanwhile, she built a house, corral, and lime kiln on the west side of the valley, and planted wheat and corn in the valley’s bottom, on the east side of the Sweetwater River.27 During this period, however, Doña Apolinaria continued to live at the mission and attended the priests and a few remaining neophytes. She hired a mayordomo, or foreman, to oversee the rancho, occasionally staying there herself for a few days at a time.28

In 1837, during one of her periodic visits to the rancho, tragedy struck. Natives from the Jacumba area attacked the neighboring Jamul Rancho, which had been granted to Don Pío Pico.29 The hostile band killed the mayordomo, Juan Leiva, and two servants, and kidnapped Leiva’s two daughters. Doña María de Los Angeles, Don Pío Pico’s mother and mistress of the rancho, fled with her daughter to Jamacha where Apolinaria gave them refuge. Friendly natives from the nearby rancheria of Sequa were summoned to help defend Jamacha. The hostile band from Jacumba, however, retreated after attacking Jamul.30

Doña Apolinaria continued to reside at the mission, leaving her ranches to the care of mayordomos. The mission, however, was declining rapidly. In 1846, the last resident priest, Father Vicente Oliva, who had remained at his post following secularization, moved to San Juan Capistrano. His move left the San Diego Mission abandoned. The buildings by this time had become dilapidated and only a very few neophytes remained.31

Soon Apolinaria would also leave. In the spring of 1846 war broke out between the United States and Mexico, and American troops occupied San Diego in July.32 In January, 1847, a company of American volunteers, the Mormon Battalion, occupied the mission.33 At this point, Apolinaria followed Father Oliva to San Juan Capistrano, abandoning her ranchos. Her first love and dedication had always been to the church and priests. The mission filled with American soldiers and, with the missionaries and most of the Indians gone, she had no reason to remain.34

Following the conquest of California by the United States, Rancho Jamacha became the property of the invading Americans. Upon the termination of hostilities, Mexican Californians were given guarantees by the United States Government that their property and civil rights would be respected. Article 19 of the Treaty of Guadalupe Hidalgo stated that Mexican Californians “would be maintained and protected in the free enjoyment of their liberty and property, . . .”35 However, despite these guarantees, a combination of political, economic, and social factors resulted in the loss of a large portion of rancho lands by their original owners or their descendants.36 The land policy of California, which favored midwestern and eastern settlement patterns consisting of small farms, became the most significant of these factors. The state land policy resulted from pressure by many newly arrived Yankee immigrants who could not accept the fact that thirteen million acres of the best land in California was controlled by only a few hundred individuals.37

Pressure from newly arrived immigrants resulted in the Land Act of 1851 that established the United States Land Commission in order to investigate the legitimacy of all land claimed under Mexican period grants. Although the law could have been justified under Article 19 of the Treaty of Guadalupe Hidalgo as an attempt to protect the claims of Mexican Californians, the manner in which it was executed violated the treaty’s spirit. Rather than a quick and speedy process, the ordeal of investigation and confirmation took decades, placing the rancheros at a distinct disadvantage.38

In attempting to validate their claims, the Mexican Californians faced several barriers. The burden of proof was placed on the rancheros. However, Mexican grants had been poorly documented and many of their original records lost, so that a number of landowners found it difficult to produce proof acceptable in a court of the United States government. In addition, the rancheros had no understanding of American legal procedures and were unfamiliar with the laws of the United States. This problem was compounded by the fact that very few of the ranchero aristocracy could speak English. Finally, the complex and lengthy process of claim validation forced many Mexican Californians to mortgage their lands in order to pay court costs and lawyers’ fees, and this eventually led to the loss of their property.39

Typical of many land cases, it was during the long wait for final confirmation to her claim that Apolinaria lost Jamacha. Early in 1852, she petitioned the United States Land Commission for the return of the rartcho.40 However, by this time events were already in motion that would result in the eventual loss of her property.

The men who would come to own Jamacha Rancho had arrived in San Diego following the Mexican War. Unlike the north, where gold seekers constituted the majority of new emigrants, military men made up most of the Americans in San Diego during the early 1850s. In April, 1849, five companies of the Second U.S. Infantry received orders to take post at San Diego. Shortly after their arrival, two companies occupied the mission.41 The following June the United States Boundary Commission arrived in town.42 Among the members of the U.S. Infantry and the Boundary Commission were many of the individuals who would affect San Diego’s history over the next decade.

A group of the newly arrived military personnel and local businessmen attempted to develop a city on San Diego Bay, known as New San Diego or New Town. Although doomed to failure, the project provided a nucleus that brought together the future owners of Rancho Jamacha. Among the entrepreneurs involved in the New Town Project were Colonel John Bankhead Magruder,43 First Lieutenant Asher R. Eddy,44 Eugene B. Pendleton,45 Frank Ames,46 and Robert Kelly.47 These men would control the Jamacha Rancho for the next twenty years.

Through the efforts of Colonel Magruder, the five men came to own Rancho Jamacha. As previously stated, at the time of the Second Infantry’s arrival in San Diego, Doña Apolinaria Lorenzana resided in San Juan Capistrano and had abandoned the property.48 When she left San Diego, Apolinaria appointed Juan Forster as her agent in charge of the ranch.49 In 1850 or 1851, Magruder obtained permission from Forster to graze the Army’s livestock on the Jamacha.50 In September, 1852, Magruder, Eddy, Kelly, Ames, and Pendleton formed a partnership and began to work the ranch.51

As yet, the five entrepreneurs had no title to the land, and Doña Apolinaria earlier that year had petitioned the United States Land Commission for the return of her property.52 On January 17, 1853, Colonel Magruder purchased the Jamacha Rancho from Lorenzana for $2,500. According to the terms of the transaction, executed through a deed and mortgage of the same date, Magruder paid Doña Apolinaria $500 in hand, the balance being due six months after the Land Commission confirmed her claim to the property.53 On March 26, 1853, Colonel Magruder sold an undivided two-thirds of the ranch to Eddy, Ames, and Pendleton for $333.34 in hand and $1,333.34 to be paid to Doña Apolinaria Lorenzana six months after the Land Commission confirmed her claim, as two-thirds of the balance owed on the property by Magruder. This transaction was also executed through a deed and mortgage of the same date.54 At this point, therefore, Doña Apolinaria had sold her property, as had many of the Mexican Rancheros, yet she still retained rights to the land through the mortgage made to her by Colonel Magruder.

Before final confirmation of her claim, Apolinaria gave up her rights to the property. The Land Commission ordered a survey of Rancho Jamacha in 1857 and issued a preliminary confirmation to Lorenzana in 1858.55 According to the Act of 1851, however, final confirmation and a patent could not be issued until the original survey had stood uncontested for twelve years.56 Doña Apolinaria did not wait, but sold her mortgage on the property, in 1860, to J. C. Keiver of Los Angeles for $800, thereby giving up all rights that she had retained to Jamacha Rancho.57 In May, 1864, Keiver sold the mortgage to Lieutenant Eddy’s brother, E. W. Eddy of San Francisco, for $600.58 Although Lorenzana now had no legal title to the property, in the years to come she would insist that she did retain rights to the land and that it had been stolen from her.59 Her claim would finally be denied when the rancho was subdivided in the early 1880s.

Until its final subdivision, Rancho Jamacha was primarily used to graze livestock. By the time Eddy, Kelly, Ames, Pendleton, and Magruder had received title to the ranch, they were already running a well-established business on the property.60 During the early 1850s, Southern California ranches prospered as they never had before. An increase of population in the northern part of the state, as a consequence of the gold rush, sent livestock prices soaring. The ranchers of Southern California quickly took advantage of this new market. No longer did hides and tallow constitute the sole source of a livestock man’s profits.61 It was this atmosphere, no doubt, that encouraged Eddy, Kelly, Ames, and Pendleton to develop the Jamacha Ranch. Colonel Magruder, although retaining control of his one-third interest, dropped out of the picture after 1853.

Under the direction of the remaining four partners, Jamacha became a prosperous and profitable ranch devoted to agriculture and animal husbandry. Robert Kelly directly oversaw the operation of the enterprise, living in the adobe Apolinaria had built on the west side of the valley and acting as foreman or manager.62 Lieutenant Eddy, along with Ames and Pendleton, provided financial backing and supplies.63 Kelly cultivated three hundred acres of land on which he grew wheat, barley, oats, rye, and vegetables such as potatoes and artichokes. Butter was made and sold in Old Town and to the soldiers at the mission.64 As a result, Jamacha Rancho became the first successful large-scale agricultural enterprise in the county. Livestock, the main concern of the business, included sheep, horses, cattle, mules, and hogs. These were purchased throughout the county for the purpose of breeding and resale.65

In September 1858, Robert Kelly terminated his partnership with the owners of Jamacha Rancho and went into the mercantile business in Old Town with Frank Ames.66 Eugene Pendleton had left town a year before and by then the New Town development was only a dream of the past.67 When Robert Kelly left Jamacha Rancho, the livestock boom of the early 1850s was quickly ending. Beef prices had begun to fall in 1855 when herds from out of state were brought in.68 By the end of the decade, ranching could no longer be considered a profitable business in Southern California. As a consequence, Ames and Eddy, the only members of the original five who remained actively involved with the property, ceased to operate the Jamacha Ranch as a business. The once large herds dwindled until, by 1860, livestock on the property included only eleven cattle, and 119 horses.69 From 1861 to 1868 it appears that they had little or no livestock on the ranch.70

Beginning in the late 1860s, ownership of the ranch began to be divided among a number of individuals, which resulted in the property’s final subdivision. In December, 1869, A. R. Eddy sold all of the Jamacha to his wife, Mary H. Eddy.71 The entire parcel, however, was not his to sell since Magruder, Pendleton, and the estate of the by then deceased Frank Ames, still held their respective interests.72

Two years later in 1871, several events occurred which further complicated ownership of the property: William Keighler of Baltimore acquired the estate of Frank Ames, including an undivided one-sixth part of the Jamacha.73 E. B. Pendleton sold a one-eighteenth undivided interest of the property to Salon S. Sanborn.74 Colonel Magruder died in Texas, leaving his share of the ranch to his estate; and the United States government issued a patent to Doña Apolinaria, confirming her title to the Jamacha Grant, even though she had given up all claim to the land a decade earlier.75 By 1872, therefore, owners of the property included W. H. Keighler, the estate of Colonel John Bankhead Magruder, E. B. Pendleton, S. S. Sanborn, and Mary H. Eddy.76

The Jamacha grant was divided even further between 1872 and 1880. The interest purchased by Sanborn passed through a series of transactions by which portions were conveyed to O. S. Sanford, N. H. Conklin, J. G. Pratt and M. G. Stockton.77 Additionally, William H. Ware purchased an undivided 1,500 acres from the estate of J. B. Magruder in 1880 and began to cultivate a portion of the Jamacha Valley.78 In the same year, L. G. Pratt purchased an additional undivided 400 acres from William H. Reighler.79

While Jamacha Rancho was split into various undivided interests, making a subdivision of the tract inevitable, ownership of the property had become even more confused and complex as a result of action taken by Doña Apolinaria Lorenzana. On December 31, 1878, Doña Apolinaria had conveyed the ranchos of Jamacha, Los Coches, and San Juan de Secua, to Monica Romero de Ruiz of Santa Barbara. However, she no longer held legal title to the three ranchos, having sold San Juan de Secua in the 1830s, and Los Coches and Jamacha, following the American conquest.80 How Lorenzana justified the sale of land she no longer possessed is not known. Considering her pious reputation, it seems unlikely she had fraudulent intentions. Doña Apolinaria must have believed that she still owned the three ranchos, perhaps as a result of the final confirmation of her claim to Jamacha in 1871.

In March, 1881, various owners of the Jamacha Rancho filed a suit in Superior Court, asking that the ranch lands be subdivided and portions be granted to the different owners, according to their respective interests. Plaintiffs in the case were William H. Keighler, N. H. Conklin, Minnie G. Stockton, and Susan G. Pratt. The defendants listed included Mary H. Eddy; Eugene B. Pendleton and his wife, Elizabeth Pendleton; O. S. Sanford; William H. Ware; Charles J. Fox, the administrator of the estate of Colonel John Bankhead Magruder; W. J. Plummer and Monica Romero de Ruiz.81

The court, after having investigated the legitimacy of the various claims, ordered that the Jamacha Rancho be surveyed and subdivided into different parcels which could be allowed to the respective claimants. Final allotment of the property was as follows:82

Contestant Plat Acres
Estate of John B. Magruder
(ordered sold by Court)
A         255.67
Minnie G. Stockton B 39.84
N. H. Conklin    
Minnie G. Stockton    
Estate of J. B. Magruder        
(ordered sold by Court)
C 667.60
N. H. Conklin D 72.00
W. H. Ware E 790.00
Mary H. Eddy F 3102.14
Mrs. E. A. Pendleton G 1890.03
W. H. Keighler H 1750.04
S. G. Pratt I 313.84

In addition, the court concluded that the claims of Monica Romero de Ruiz and E. B. Pendleton were not valid.83

Following the property’s subdivision, Jamacha Rancho would no longer be considered a single tract of land. Over the next few decades, various portions of the ranch would be developed in different ways. The southern portion of the property, which included parts of plats “H” and “I,” would become a basin for Sweetwater Reservoir, while those portions lying within Jamacha Valley, plats “A,” “B,” “C,” ” D,” “E,” and “F,” would be transformed into productive farmlands supporting a small agricultural community.84

With the final subdivision of Jamacha Rancho, Apolinaria Lorenzana’s claim to the property, which she had by then confirmed on Monica Romero de Ruiz, was denied. However, the evidence clearly indicates that Doña Apolinaria had already given up all rights to the ranch in 1860 when she sold her mortgage on the property to J. C. Keiver of Los Angeles. The loss of Jamacha Rancho was, therefore, a result of her own actions and not the consequence of “some legal hocus-pocus” as has been claimed.

Rather than the victim of a fraudulent scheme, Doña Apolinaria appears to be typical of those members of the ranchero aristocracy who lost their holdings as a result of the Land Act of 1851. Like many of the Mexican rancheros, she probably did not understand the complex and lengthy process through which her property would be restored, and sold her rights while waiting for final confirmation.85

In her memoirs, Doña Apolinaria Lorenzana does not mention any Indians living in the Jamacha Valley during the 1830s. However, she does state that in 1837, when Jamul Rancho was attacked, three of her Indians servants were from San Diego and nearly all the rest were from Sequan. It seems that if there had been more than a few individual natives residing in the valley, they would have been employed on the ranch or at least mentioned by Lorenzana. Perhaps by this time, the inhabitants at Jamacha had merged with those at Sequan.

Most were very badly drawn and roughly surveyed. Lorenzana’s diseño, shown in Figure 1, is oriented incorrectly. The Sweetwater River flows through Jamacha Valley from the northeast to the southwest, not from east to west as shown on the diseño. Furthermore, the narrow entrance to the valley shown on the north of the diseño, is undoubtedly the canyon through which Highway 94, or Campo Road, now passes west of present day Jamacha Junction and is located on the west end of the valley rather than the north.

27. If the diseño is oriented correctly, as explained in the previous note, with the Sweetwater River flowing through Jamacha Valley from the northeast to the southwest, the house is located on the west end of the valley near present day Jamacha Junction.
