I knew Dan only slightly as the father of Michael, Daniel & Kimm. He was separated from wife, Louise M. (Hardesty), at that time and later divorced. He later married friend Sharilyn (Lerch) Tunnell in June 1976. Dan's parents were Sibley (SR.) and Johanna Cox. He had a sister: Ruth Elizabeth, and a brother: Sibley (JR) Cox. He was born in Oakland, California.
