About Sunnyvale

When the Spanish first arrived in the 1770s at the Santa Clara Valley, it was heavily populated by Native Americans. In 1777, Mission Santa Clara was built by Ohlone who converted to Christianity. In 1842, Rancho Pastoria de las Borregas was granted to Francisco Estrada and his wife Inez Castro.

This has been translated as "Ranch of Posolmi and Lake of the Colors," or more commonly known today simply as "Posolmi." Sunnyvale is located at .
