José de los Reyes Berreyesa

José de los Reyes Berreyesa (6 January 1785 – 28 June 1846) was a Californio military officer and ranchero. He was born at Mission Santa Clara de Asís in Las Californias province of the Spanish Viceroyalty of New Spain (colonial México).

He was the third child and first son in the family of María Gertrudis Peralta and Nicolas Antonio Berrelleza. He served as an army sergeant at El Presidio Real de San Francisco.

In 1805, he married María Zacarias Bernal at Mission Santa Clara. The couple had 13 children during 1807–1833, with 10 living past infancy. Andres Castillero also claimed the mercury mine was part of his land.

Robert Walkinshaw and some other men squatted on the rancho land in February 1845, and began to take lumber and limestone away to sell in August.

Bear Flag Revolt In 1846, during the Bear Flag Revolt, three of the Californio sons of José de los Reyes Berreyesa were imprisoned by John C. Frémont in Sonoma, California, where one of the sons, José de los Santos Berreyesa, had been serving as alcalde. Accompanied by two cousins, twin sons of Francisco de Haro, the 61-year-old father went to see how his sons were being treated in prison. After they landed their boat in San Rafael, the three men were shot and killed by three of Frémont's men, including Kit Carson,

Later, Carson told Jasper O'Farrell that he regretted killing the Californios, but that the act was only one such that Frémont ordered him to commit.
