Rancho Santa Gertrudes

A former site of Nacaugna, the rancho lands included the present-day cities of Downey, Santa Fe Springs and the northern part of Norwalk.

[4] Lemuel Carpenter (1808–1859), who had married Maria de Los Angeles Dominguez, a niece of Josefa Cota, bought the rancho in 1843 from Josefa Cota, his aunt by marriage.

[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.

[9] A claim for part of Rancho Santa Gertrudes was filed by Thomas Sanchez Colima with the Public Land Commission in 1852,[10][11] and 3,696 acres (15.0 km2) of the grant was patented to Thomas Sanchez Colima in 1877.

[13] The southern border between Ranchos Santa Gertrudes and Los Coyotes exists today as Leffingwell Road.
