The land was originally granted to Nicolás Tolantino Antonio Berreyesa by the alcalde of San José, Pedro Chaboya, on May 6, 1834. A neighboring parcel was granted to José María Alviso by the governor of Alta California, José Castro on September 23, 1835. Alviso built the first story of the ranch house on the north east corner of the property and moved his family there. 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. As required by the Land Act of 1851, Berreyesa filed a claim for Rancho Milpitas with the Public Land Commission in 1853, but was rejected. Some members of the Berreyesa family went mad defending their land: one son ran into the hills, another died in an asylum. The family was evicted from the rancho. Alviso hired an American lawyer to survey his land, and the new borders of the rancho included much of Berreyesa's claim. Alviso filed a claim for the grant with the Land Commission in 1852, and the grant was patented to Alviso in 1871. Both Californio-held parcels were subject to a rush of American squatters in 1852. Berreyesa and his three sons were tricked by Anglo settler James Jakes who told them they could cement the Berreyesa claim by building four new homes on outlying areas of the property and occupying them in a similar manner to the new squatters. Jakes seized the vacated Berreyesa adobe and claimed the whole grant for himself. After Alviso died on 1853, his widow, Juana Galindo Alviso, rented a home to two of the Berreyesa sons. When she married the rancho manager, Jose Urridias, a native of Sonora, he made them leave. Eventually the Alviso family had to sell off most of the land to pay court fees to fight off American squatters.
