HVAC Cleaning in Alamo, CA

Humans have lived in the area for over 5,000 years. 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.

In 1843 much of the Alamo, Las Trampas and Tice Valley areas were granted to brothers Inocencio and José Romero. It was called Rancho El Sobrante de San Ramon. Because of missing title papers, the brothers lost their ranch in American courts in 1857.
