Hello Robin: many thanks for the reply. It helps a lot, and it doesn't help!! I would love the names to be the right ones for me as it clears up a problem I have and clears the way to pursue more Bunyans! My Florence (my grandmother) is shown as 20 years old in 1907 on her marriage certificate, which would make her born around 1887. Does that tie in with you? I have a feeling your George and Elizabeth were married after that date (not that that means anything I suppose). Do you have their wedding dates? Marylebone seems to be the family area of London at this time too. Florence lived at Lisson Grove when she got married.
Of course, if the names are what I want, it means we are related!
