The Suisunes (also called the Suisun and the "People of the West Wind") were a Patwin tribe of Wintun people, originating in the Suisun Bay and Suisun Marsh regions of Solano County in Northern California. Their traditional homelands stretched between what is now Suisun City, Vacaville and Putah Creek around 200 years ago. The Suisunes' main village, Yulyul, is believed to be where Rockville, California is located today. Father Abella, visitor to the tribe in 1811, indicated they resided in the present location of Fairfield, north of the Suisun Bay.[1] One of the Suisunes' primary food sources was acorns. Their diet also included fish as well as miner's lettuce. Their huts (as recorded by the Spaniards in 1817) were conical wikiups made of rushes or tule thatch.
