Hello, I was raised in Mendocino Co. My uncle Leith Johnson married Ermma Eileen Ledford. She was a relative of the family you spoke about she died in Navarro in 1966. The Ledford's lived in Yorkville in Mendocino County. It is close to the Sonoma County border. The Ledfords also lived in Cloverdale which is on the Sonoma Co. border. So the to places were close. The Ledford family drove stagecoach around the parts. I read alot of history about this area. There is a book I have that has families of Cloverdale. Published by Cloverdale Historical Society. It has the Ledford families in it. The address for the Cloverdale Historical Society is 126A North Cloverdale Blvd. Cloverdale,Ca. 95425 Phone number is (707) 894-2067.
