Hi Ian,
I'll send you a PM with my contact details, Victor and Muriel did emigrate to Canada, but they married in Belfast.
In 1933 they were living in ballyhay, outside Donaghadee, where Victor was a dairyman, prior to that he was also a milkman in Belfast, my mother remembers him working in the family dairy in Mountview street in Belfast when she was a child in the 1940's.
I understand James and Nora also emigrated to Canada with their son Gordon. They may have returned at some time though, I'm told Gordon Hamilton had three children in Canada, but since he died my mother has lost touch with them.
The above thread sums up what I know about the Hamilton's going backwards, Victor's father was a William Hamilton, mother was Margaret Gordon. then James Hamilton and Samuel Gordon were his two Grandfathers. That's where I'm stuck until next time I can get to Belfast and do some more research.
Gordon.
