Bill Weber: I am a Descendant of Luis Maria Peralta (1 of 4)
Bill Weber talks about the history of the family of his maternal great-grandmother, whose great-grandfather was Luis Maria Peralta, a sergeant in the Spanish Empire’s army, who was granted almost 45,000 acres of land in the San Francisco East Bay.

EaRTh staff conducted an interview with Bill Weber, an artist (predominantly, surrealism and murals) based in the San Francisco East Bay, California, United States, about his family history, which includes being a descendant of Luis Maria Peralta, who was granted almost 45,000 acres of land in the East Bay by the Spanish empire, in recognition of his service as a Sergeant in their army.
EaRTh: Hello, we're here with Bill Weber today. Hi Bill, how are you?
Bill Weber: Good, how are you doing?
EaRTh: I'm well. We're here to talk about your art, but I wanted to start by understanding your family history. Could you go into that a little bit, please?
Bill Weber: Sure. My fourth great-grandfather is Luis Maria Peralta, who's this gentleman up here [pointing to one of his paintings hanging on the wall behind him]. And he came here in 1776 with [Juan Bautista] De Anza; they put him in charge of Mission Santa Clara, and after 45 years of service in the Spanish Army, they gave him all the land from the middle of San Leandro to Albany Hill to the top of the hills to the bay… [that became] the Peralta Ranch.
EaRTh: Can you provide a bit more historical context for this?
Bill Weber: Well, the Spanish Army, in 1820, gave [Luis Maria Peralta] the land grant.
EaRTh: So, just to provide some context for our global viewers, Spain had colonized California from the 1500s onwards?
Bill Weber: Yeah, from the late 1500s, yes.
EaRTh: And so, in the late 1700s, this northern part of California [called Alta (upper) California by the Spanish empire] belonged to Spain? And your ancestor, Luis Maria Peralta, was in the Spanish Army?
Bill Weber: Correct, the Spanish Army.
EaRTh: And he was given the land out of gratitude?
Bill Weber: Yeah, as payment for his work in the Spanish Army.
EaRTh: And do you know what his work was in the Spanish Army?
Bill Weber: Well, he was in charge of Mission Santa Clara.
EaRTh: And what does that mean?
Bill Weber: Well, actually, he was like a soldier, and he protected the mission from the Indians. And he was supposedly right under the governor.
EaRTh: The governor of California, to Spain?
Bill Weber: Yeah, he was one of the highest ranking officers in California.
EaRTh: So, his job was to keep the Native Americans out of the mission?
Bill Weber: Just to maintain the mission. A lot of the Native Americans worked at the mission. The Native Americans took care of his cattle that were on his ranch here.
Box 1: Historical Context of the Colonization of California by the Spanish Empire (provided by EaRTh)
Born in Spain in 1485, Hernan Cortes moved to Cuba in 1511, where he assisted Diego Velazquez in his conquest of the island. In 1518, Cortes persuaded Velazquez (both Conquistadors) to make him commander of an expedition to Mexico, which the Europeans had recently ‘discovered’ and believed to contain great wealth. Shortly before Cortes left, Velazquez canceled his commission. But Cortes ignored him and set sail anyway.
At the time, the major civilization in Central America was that of the Aztecs, led by Montezuma II from the Aztec capital, Tenochtitlan. Shortly after Cortes’s arrival, he took Montezuma II hostage and demanded a huge ransom from his people. In the meantime, in 1520, Velazquez sent an expedition to capture Cortes. As Cortes fought the expedition, the Aztecs revolted. Montezuma II was struck by a stone and died, but the Spanish were driven out of Tenochtitlan, incurring heavy losses.
Cortes returned in 1521, laying siege to Tenochtitlan for three months. A new Spanish settlement, Mexico City, was built on the ruins of Tenochtitlan and became the center of the Spanish empire in the Americas. Cortes secured control over Mexico, inflicting great cruelty on the Indigenous peoples. In 1523, he was named governor and captain general of New Spain. However, in 1528, amid Spanish fears that Cortes was becoming too powerful, he was forced to return to Spain.
Cortes returned to Mexico several years later, when he continued to explore Central America, hoping to find a strait from the Atlantic to the Pacific. [1] Cortes obtained information about the peninsula on the west coast of the Americas from Aztec nobles in Mexico City. By the end of 1519, Cortes had obtained sufficient knowledge of the gold-bearing regions in the area of the Gulf of Tehuantepec to interest him in ordering the occupation of this area (later named California). By 1530, Cortes’s men had reached Baja (lower) California and began colonizing it. [2]
Not until 1542, did Cortes’s men sail north to Alta (upper) California [the portion north of the Californian peninsula that is now part of the United States of America]. However, more than two hundred years passed by before Spain made any concerted efforts to colonize Alta California. Not until the Seven Years War (1756-1763) realigned European alliances — and, therefore, influenced European colonizing strategies — did Spain seriously attempt to assert control over Alta California. They did this through a combination of military forts (presidios) and mission churches overseen by Christian Franciscan priests led by Junipero Serra. [3]
In 1769, a small number of Catholic priests, accompanied by a hundred Spanish soldiers, landed in San Diego (the southernmost large city in present-day California (United States)) to convert the Indigenous people to Catholicism and occupy California, as commanded by the pope and the Spanish empire. Serra led the ‘Sacred Expedition,’ i.e., build a chain of missions along the coast of Alta California, block invasions by British and Russian explorers, and profit from the labor of unpaid Native Americans, who — he hoped — would transform the settlers’ lands into orchards and vineyards. Spain did not invade California for gold or silver, as it had done in Mexico and Peru. Instead, Spanish soldiers and Mexican settlers were ordered to form a human border to protect the silver mines in Northern Mexico from the Russians advancing from the north. Enslaved and conscripted Native Americans worked in the colonizers’ silver mines and grew fruits and grains in "theological plantations of conversion" to feed Spain’s soldiers and priests. The Spanish deliberately planted the missions near traditional native American springs, along riverbanks, next to Indigenous villages, and often on sacred sites. [4]
