Mary Adelyn and Wendell settled in Wichita, KS, and had three children – Steve, Susan and David. In 1966, the family moved to Edmond, OK, and Mary became an active member of St. Mary’s Episcopal Church. Among many things, she was part of a group which created a number of banners for the Church.

Mary will be remembered for her kind, caring manner and her funny sense of humor. Even in her last year, she always had compliments for others. She was active later in life supporting the Seminole Nation Museum in Wewoka, OK, in honor of her father’s lifetime work with the Seminole People. In lieu of flowers, the family would suggest a contribution to the Seminole Nation Museum, 524 S. Wewoka Ave, Wewoka, OK 74884.
