Hello Avril,
There seem to be several previous posts about your William....I am going to add some additional information from those posts to help other researchers.
Parents were Samuel and Edith
William had been a miner in Wales
Came to To Canada on 15 Aug 1928 on Empress of France leaving Southampton for Quebec. Likely a harvester.
Jacquie found a possible return trip for a William T Potter, harvester, back to Southampton, England on the Metagama 28 dec 1928.
William had a relative in Canada called Charles Hippard….who seems to have come to Canada in June of 1928. Charles died in Alberta 1992. I just found an obit for him in the Lethbridge Herald.
There is a tree for him on familysearch and I believe there is a tree on Ancestry. In an earlier thread, I posted a link to a short bio of Charles …on the ourroots site (in a history of Raymond Alberta, at page 474). The old link no longer works. Here is a new link to the bio. It says Charles moved to Raymond Alberta from Saskatoon in 1945.
https://cdm22007.contentdm.oclc.org/digital/collection/p22007coll8/id/1202146/rec/2Have you followed up on Jacquie’s lead – that William may have returned to the UK at the end of 1928?
Have any of the trees showing Charles Hippard shed any light on the whereabouts of William?
