The story
from WikipediaRead it all ↗Alamo was first inhabited by the Tatcan Indians over 5000 years ago. The Tatcan Indians, a Bay Miwok tribe closely connected to the Saclans of Walnut Creek, lived in Alamo in the eighteenth century.
After Mission San José was founded in 1797, its grazing area stretched throughout the San Ramon Valley. The Mexican land grant Rancho San Ramon was deeded to Mariano Castro and his uncle Bartolo Pacheco in 1833. It covered modern-day Danville and Alamo. Castro owned the northern half, which included Alamo.
