My grandfather was Walter Edward Fray. His siblings were all of which you described. However, Walter and his wife Rachel Ann Jones (my grandmother) came to Canada in 1949 from Swansea on the Empress of Canada. They came with John (my uncle). My mother came over sooner on the Aquatania in April of the same year.
Any questions of them and the Canadian connection please follow-up as I am just starting the family tree and would appreciate anything cousin!!! Ha!
