Domínguez's original grazing permission stretched from present-day Compton to the Palos Verdes Peninsula but did not become a title to land until it was "re-granted" in 1822 in the Mexican era to Juan José's nephew and heir, Cristóbal Domínguez. Cristóbal died soon afterward, but his three sons settled on the ranch, building
adobe homes. 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. The Sepúlveda family was awarded known as
Rancho de los Palos Verdes that later became the cities of the Palos Verdes Peninsula, as well as portions of Torrance and San Pedro.
