Hi Rachel;
I'm still not sure of who Joseph Emlaw was. I think I know who he was as I've pretty well eliminated and accounted for all the Joseph Hamelin/Emlaw's born in Quebec between 1880 and 1890, except one. He had three brothers (plus a sister or two) and the brothers all emigrated to New York State.
But Oliver was NOT his son, as Joseph and Mary were not married in 1811.
I've spent considerable time, money and effort on that family, my dad's first wife being a daughter of Marie Louisa Emlaw, grand-daughter to Joseph.
As of today, I have quite a bit on the Emlaw's but there are still some loose threads to tie. I should be able to put all that on the Internet this year. I have some in my own Family Tree and others (the Americans) in another Family Tree)
You'll see some surprises.
Frank
P.S. Who is your husband's father? I must have the family.
