Thank you peckwoman. The 1939 'census' is a strange one.All 4 of the family would have been living there at the time, so I'm assuming that all of them, excluding Emily Annie were staying elsewhere on the relevant night, though I couldn't find them recorded anywhere! The information about Walter Sydney's ancestors is fascinating. My mother, Flora Fentum, was Walter Sydney's daughter from his second marriage to Gladys nee Richards. We have been trying to trace the Richards family line as we thought that there was a link, apart from Gladys, to the house in Crystal Palace Road. It looks like we were looking at the wrong family line!
