The grant encompassed present-day Penngrove, Cotati and Rohnert Park. "Cotate Rancho is a part of the Vallejo Township which is the plain between Sonoma Mountain and Petaluma Creek San Pablo Bay, and an east and west line dividing the tract from Santa Rosa Township." In 1849, Dr. Thomas S. Page, of Cotati, bought Rancho Cotate. Over time, the property was broken up and sold off piecemeal to incoming settlers.The town of Rohnert Park was named after the Rohnert family, which owned the Rohnert Seed Farm. In 1929, a successful businessman, Waldo Emerson Rohnert (1869–1933), a native of Detroit, Michigan, purchased a large ranch in the area and minimized flooding in the fields with a crude drainage system.
