From Virginia Loomis I had that Otis and Fannie had a son Paul born after 1930, with no exact birthdate. There is a Paul D. Pettit listed in the Kentucky birth index as born 24 Dec 1936 in Grant Co., mother’s maiden name Fannie Jump. I cannot find any better match, in particular, no Paul Pettit with the mother’s maiden name being Delf.

The California death index lists Paul Douglas Pettit, born 24 Dec 1936, died 12 Feb 1995 in Orange Co., mother’s maiden name Delf.
