Thank you slowhands for delving into this!
All I had found for Frances E B was a marriage registration 1910... but not the spouse... so this may be it... although if she died in 1966, that is after my grandfather and my grandmother did not have Eliz listed as still being alive.
I doubt that Rosalie Babb is the right one.. as Bickerton was her middle name and not Brenda.
See what happened once they left F of D for Kent!
