He married Dargie J. Palmer in Oct. 1975, both were living in Amboy, Illinois at the time. Dargie was quite a bit younger then him and she was born in 1958.
It appears they were divorced by 1977. Dargie got remarried and she and her new husband Gerald W Arwood had a son on June 17, 1977.
Looks like Gaylor may have been named after his grandmother. Gerald Patrick Horne's parents were Arthur E Horne and Evelyn Gaynor.
