We know from the 1939 Register that Florence married a SUTTON.
There are two possible marriages of a Florence SMITH to a SUTTON: Florence to Harry SUTTON in Q4 1942 in Blackburn, and Florry to Eric SUTTON in Q1 1943 in Darwen.
Mrs Florrie SUTTON died in Blackburn on 21 Aug 2007; the record confirms her birth date as 30 Jul 1920. A Florry SUTTON died in Darwen in 2000 but had the wrong birth date. Given the spelling, this was most likely Eric's wife, meaning that Harry was Florrie's husband.
