on the
Electoral Lists that Shane refers to there are two couples that could match in 1939, if James and Annie were still living
There were 16 James and less Ann* and just two with matching addresses
17 Brian Avenue and 14 Abbey Cottages
If the reference for the marriage is correct their marriage certificate should state their fathers' names and pin point them on the 1911 census for you and help to trace back further
For
James Caffrey I searched on the census for CAFF*, James, age 13+/-5, and there are only 6 results which looks good for researching further
