I'm probably clutching at straws here.
In 1921 Florence was a visitor to an address in Wanstead. (So possibly London based at the time)
A 1918 electoral register has a Florence May Jones and David Jones at 4 Powis Lodge, Vicarage Park
Year 1919 & 1920 at
4 Powis Lodge Vicarage Park there’s a
Lizzie Jane Jones at the same address with Florence & David.
Do you know who she is?
Is this the same couple on 1911 census address 4 Vicarage Park Plumstead
