Hi-
What a coincidence! I just removed your William and Euphemia from my tree, where I had added it as a possible match with my William! There were altogether too many folks named Nichol, Beattie, Laidlaw, and Grieve in that area. And they all moved to Ontario, Canada and continued the confusion!!
I have birth records for several of your William/Euphemia's children. I don't think I have anything on either of their parentage, but I will look through my notes and snippets and see if there's anything there.
Cheers,
Carrie
