Norman was born on January 18th, 1907 in Whitehaven.1
Birth Notes
Probably not born in Cheshire. Can only find 2 in the whole of the country after 1880:
Births Mar 1907 CADDY Norman Whitehaven 10b 715 Births Jun 1910 CADDY Norman Stoke T 6b 22_
The first one matches up with the DOB on the death record, so this must be him (and confirmed by his grandson Mark):
Name: Norman Caddy Year of Registration: 1907 Quarter of Registration: Jan-Feb-Mar District: Whitehaven County: Cumbria, Cumberland Volume: 10b Page: 715
Died a long time before Edith. Probably died in Heswall.
Name: Norman Caddy Birth Date: 18 Jan 1907 Death Registration Month/Year: 1976 Registration district: Birkenhead Inferred County: Merseyside Volume: 37 Page: 0760
General Notes
If Norman married Edith when he was 57, then he had probably been married before. Ancestry family trees have the same Norman Caddy married to Jane Stephenson (b.1901). Records confirm this is an earlier marriage, but here are no records for Jane's death, so maybe divorced.
If she did divorce, then there is another marriage for Jane Caddy, and its in Cockermouth, so most probably her. Se married William B Messenger in 1975.
The same tree has Norman's mother as Lucy (b.1882).
Connections & Relationships
Marlee Edmonds had some other social relationship with Norman.
