In 1855 Antonio Maria Lugo, partitioned the Rancho—reserving a homestead for himself—among his sons, José Maria, Felipe, Jose del Carmen, Vicente and José Antonio, and his daughters, Vicenta Perez, Maria Antonia Yorba, and Merced Foster. In 1860 Merced Foster and Vicente Lugo sold their respective portions to parties who immediately resorted to subdivision and sale in small lots. The first deed is from Isaac Heiman to David Ward, dated June 21, 1865; followed by other sales in 1865 and 1866.
In 1908 Michael Cudahy acquired the remaining 2,800 acre (11 km2) Rancho San Antonio. He subdivided the ranch and sold it as one acre (4,000 m2) lots. This area was incorporated in 1960 as the City of Cudahy.
