Hello Pamela, Alexis Urquhart married Genevieve Desloges on Nov. 26, 1822. One of their children, as you say, is Sophie Urquhart who married Francis Robert. Francis and Sophie are my G-G-Grandparents [I have his picture].
As I look through, I see mostly Scottish, French and English. I am sorry to tell you that I don't see any Native American in this part of your line.
Would you have the parents of James Urquhart b. between 1746-1766? Nancy
