Yes he was in Upper Canada (Ontario) in 1852. Think he married Helen Lumsden there, but no marriage cert. She went by the name of Ellen Philips(Previous married name). She and her children of which 2 are his, do not turn up again in census' until 1861. Have all the details concerning William T Keith and the numerous things he got up to as well as al his children from both relationships.
His father William Keith is the one i am trying to find details on as well as his mother mary taylor.
In Upper Canada William T is entered as Taylor William K, Innkeeper, Scotland, W.P, 25, M.
When he went there i do not know, who he went with i don't know either but it's a good possibility he went there with parents and possibly siblings.
