José María de Jesus Alviso (November 19, 1798 – June 18, 1853) was a Californio ranchero, soldier, and politician. He served as Alcalde of San José (mayor) in 1836 and was the rancho grantee for Rancho Milpitas. Alviso is considered the founder of the city of Milpitas.
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.[4] 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.[5][6] Further clarification comes from the Supreme Court appeal United States v. Jose Antonio Alviso (1859). Ignacio's son Jose Maria was granted another rancho, Rancho Cañada de Verde y Arroyo de la Purisima, in 1838. Jose Antonio Alviso was known to be Ignacio's eldest son. The appeal mentions that Jose Maria Alviso who made petition in 1838 for the rancho was his brother.[7]
