History

The Mexican government granted Rancho Cotate to Captain Juan Castaneda in July 1844 for his military services in the region. The grant encompassed present-day Penngrove, Cotati and Rohnert Park. Cotate Rancho is a part of Vallejo Township which encompasses the plain between Sonoma Mountain and Petaluma Creek, San Pablo Bay, with an east–west line dividing the tract from Santa Rosa Township."

Rancho Cotate was sold in 1849 to Dr. Thomas S. Page of Cotati, and eventually broken up and sold off piecemeal to incoming settlers.

The first European settlers in the Penngrove area were David Wharff, W.J. Hardin, and J.M. Palmer, who arrived in 1852.

In October 1870, the San Francisco and North Pacific Railroad completed the first railroad from Petaluma to Santa Rosa, running through Penngrove.
