I have no dates for Thomas, but according to my mother, he was originally from England. His daughter Flora Locke, born in Kidderminister, England, married my great-grandfather Robert H Lyttle, in Ontario. I have her death being in 1956. I'm not sure if this helps but I hope it does. My mother is going to talk to one of her cousins, Ethel Locke to see if she can shed more light on this for me.
