William Henry Jones married my second cousin Hannah Ellen Bennett in Barnstaple in 1930.
He was born in Barnstaple in June 1908.
I have identified him in the 1911 and 1921 census and the 1939 Register. I have found the admission record to his primary school in 1913 and his joining the Woodworkers Trade Union in 1927.
Hannah Ellen died in Hove, Sussex in 1993. Significantly, her 2 married daughters were living in Brighton.
Despite exhaustive searches of FMP, Ancestry and Family Search, I have been unable to find a definitive death record for William Henry.

William Henry's father was William John Heames Jones, also born in Barnstaple in 1888.
I have found his records in the 1911 & 1921 census and the 1939 Register, plus naval service records for 1907 - 1927. I know that he married Mary Dennis in 1908 in Barnstaple and that she died there in 1968.
However, I have been unable to locate a death record for him also.
I would be grateful to receive any suggestions as to how to solve these tricky questions.
regards,
John Bennett
