The image of the marriage of Frederick Cocroft and Maud Pember can be found on Anc...y.The address that both parties give is 12 Pemberton Terrace. Maud's father Harry Pember, a French Polisher. Frederick is a soldier.This same address can be found on the incoming (to England) passenger list for the 1932 trip that Maud and her daughter took. Perhaps this might help to connect a few dots.Frederick served with the Canadian Army (CEF) in WW1. This link is to his complete digitized service record (courtesy of Library and Archives Canada). There are 33 pages. It will be very slow to download.http://central.bac-lac.gc.ca/.item/?op=pdf&app=CEF&id=B1833-S023It appears that the daughter named in Don's obit has a tree on Anc....y. If you have a sub, perhaps you might be able to make contact with her. She has Frederick Cocroft and Maud Pember as parents to D M. She also has a death of 2018 for D M but no details to corroborate the info so I have chosen to just use her initials.PB
