Not sure if you are still looking for information on Nancy Roleson but figured I'd write this anyway.
Nancy Roleson (my ggg-grandmother) b. June 1832 and died in 1920. Nancy married Jacob Rutan (b. November 1829, d. 1905) in 1853. Family stories say she went missing when visiting her daughter and no one knows what happened.
Her mother was Mahitable Ann, a full blood Indian. Mahitable was born in 1817 and died June 9, 1890. She is buried in Beemerville Cemetary. Family story regarding Mahitable is she was raped by an Indian chief and ran away. John and Nancy Roleson took her in and helped raise her daughter Nancy.
