 Confusingly, Alviso had a cousin named José María Alviso who was born in 1807 to Ignacio Alviso and Margarita Bernal and baptized at Mission Santa Clara.However, as Alviso descendant Bart Sepulveda pointed out, since the grantee of Rancho Milpitas had served as a soldier starting in 1819, a 12-year-old would be too young to be the person in question.Further clarification comes from the Supreme Court appeal "United States v. Jose Antonio Alviso" (1859).
