Hi folks,
Vbain is correct regarding the ports of entry to Canada. Quebec City was/is another significant entry point for new Canadians. My g-grandparents with thier family sailed in 1907 from Liverpool to Montreal, Quebec and then settled in Stoney Creek & Vineland, Ontario (the outskirts of Hamilton). My grandfather did cross the Canadian-USA boarder (as many did back then, and still do) for a while when he was a young man. But, in the end he did move back to Hamilton where he married and spent the rest of his life. I'm not saying this is the same as your ancestor, but it is a likely possibility. He may have either done that, or stayed in Canada or moved to the USA as my g-uncle did when he boarder crossed into the USA to become a resident there - he ended up in Rochester, NY. He could have gone back to the UK as well.
Anyway, what I am saying is keep your sites open to the many possibilites. There is a good chance he stayed in Stoney Creek. In that case, another contact you may want to make is the Hamilton Genealogy group, can't recall their proper name at the moment. I believe they have a query section on thier website and may be able to help you directly otherwise? The RAOGK have a few volunteers in Hamilton and area as well.
Just another thought - perhaps you can contact the public libraries to see if Robert shows up in the city directories?
Do you know which occupation Robert had when coming to Canada. That may help in finding him.
Cheers, JDC
