The Ohlone living today belong to one or another of a number of geographically distinct groups, most, but not all, in their original home territory. The Muwekma Ohlone Tribe has members from around the San Francisco Bay Area, and is composed of descendants of the Ohlones/Costanoans from the San Jose, Santa Clara, and San Francisco missions. The Ohlone/Costanoan Esselen Nation, consisting of descendants of intermarried Rumsen Costanoan and Esselen speakers of Mission San Carlos Borromeo, are centered at Monterey. The Amah-Mutsun Tribe are descendants of Mutsun Costanoan speakers of Mission San Juan Bautista, inland from Monterey Bay. Most members of another group of Rumsien language, descendants from Mission San Carlos, the Costanoan Rumsien Carmel Tribe of Pomona/Chino, now live in southern California. These groups, and others with smaller memberships (see groups listed under the heading "Present Day" below) are separately petitioning the federal government for tribal recognition.
