Leslie Wales played Peggy Clarke in season 3's "Blessed Are They." I liked her kindness and spunk!

Leslie's acting career spanned four years, from 1961 to 1964. She appeared on The Real McCoys, My Three Sons, and Rawhide, among others. I couldn't find information about what she did after her time onscreen, but I did find out that she is still alive.
