I'm tracking the same family. Robert and Jean's son Robert born Nov. 1840, was living with my daughter in law's ancestor Ann (Wylie) Wilson in 1851. He is listed as her nephew.
My search is for the parents of Ann (Wylie) Wilson, so I thought by tracing the nephew Robert I could find Ann's parents. Problem is that Ann Wylie married James Hardie Wilson, and so with Robert Wylie marriage to Jean Wilson, now i don't know if nephew Robert is a nephew on the Wylie side or the Wilson side or both!
I know the parents of James Hardie Wilson but have not been able to find if Jean Wilson's parents are one and the same.
However I am pretty sure that Robert Wylie (who m Jean Wilson) had brothers John and Thomas.
Can we put our heads together to try to find the parents of WILSON and WYLIE?
Lorine PS I live in Ontario, perhaps I can help with your Margaret who came to Canada?
