Hi, Have you considered purchasing the 1955 marriage certificate for George W Parish and Doris Hunt. It would/should confirm fathers names of both parties and their own ages. Iv'e a feeling that George William Parish died in 2000 aged 86 in Surrey Northern. His dob 4.10.1914 but this is only speculation.

Added There's also a George William Parish died 1973 Sutton with a dob 4.10.1912 exactly 2 years before the other one. (this one has a probate record)
