Years before she became the first woman elected chief of the Cherokee Nation and decades before receiving the Presidential Medal of Freedom, Wilma Mankiller was a powerful advocate for American Indian families in the Bay Area.

Mankiller died Tuesday at her home in Tahlequah, Okla., the city where she was born. She was 64.

The tribal leader grew up in a housing project in San Francisco's Hunters Point neighborhood and worked in Oakland in the 1970s. Her family moved to the Bay Area in the 1950s as part of a government relocation plan for American Indians.

As a young woman, Mankiller helped develop programs on both sides of the Bay for people struggling to adjust to life off the reservation. With few other American Indians in their schools and neighborhoods, relocated children and families often felt isolated and lost, said Janet King, who directs a program at Oakland's Native American Health Center for children who have experienced trauma.

"Native children were dropping out at the elementary school level," King said.

King said that Mankiller was instrumental in creating "another kind of community" for American Indians and that she created places for children to learn about their history in a way that wasn't taught in public schools.

"Wilma knew how difficult it was to go to school as a native person," King said.
