Re: Genery we are in Preston Lanc's England
I have an index of all Gen(n)ery's born,married died from 1837 but I was unable to find entries for your two names during the 1950's or earlier.
I do have details of families from London including my own.
Do you now the father's name?
Or what part of London?
When was Ethel and Rebecca born?
If there are any further clues let me know and I'll do my best to help if I can.
Hope to hear from you soon
