Rancho San Pedro

Rancho San Pedro was one of the first California land grants and the first to win a patent from the United States.

The following year Manuel Domínguez, eldest son of Cristóbal Domínguez, married María Engracia de Cota and commenced a successful career raising cattle and serving in a variety of elected and appointed offices in Los Angeles.

For many years, a portion of the Rancho San Pedro land grant was contested between the Domínguez and Sepúlveda families through various appeals to Spanish Governors and lawsuits from 1817–1883 and was eventually partitioned into seventeen parcels in 1882.

[5] With the cession of California to the United States following the Mexican–American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.

[10] In 1869, Union Army Major General William Starke Rosecrans bought 16,000 acres (65 km2).
