Thankyou Sandra I think you nailed it all that’s remaining is to find out is where In Scotland Allen was born and when he immigrated . That’s a hard one thankyou again
I’ve only scanned through the posted information (hubby is watching tv and I can’t think)

but…
from the quoted details, I believe Allen was born in Ontario, and his parent(s) were of Scottish descent or were actually born in Scotland. At least that’s what I’ve discovered about all of my ancestors on Canadian census returns (born in Ontario, either stating English or Irish nationality).
Did Allen claim to be born in Scotland in other census years? If things quiet down here, I’ll look through your thread to see where he stated that he was born.
