Thank you for clearing a few things up for me. Lottie or Charlotte McWilliams was my g.Aunt, b. 1849 in Sunnidale Township, Simcoe, Ontario. All I had to go on was an old letter that said "Lottie married ---- Allerd(?)and had four daughters, moved to S. Dakota".

I did finally find him in the 1910 Census. Do you have any more information on his descendants? I am trying to flesh out the McWilliams family tree and that includes the daughters families. Thankyou.
