Im trying to track my native american roots and Im looking for help. i keep getting stopped at the Canadian boarder between 1910 and 1920. I am looking for information on my great great grand mother. From what i was told she was lost from the tribe as a young girl and picked up my a french family in canada. and then later immigrated to the united states. All i have is a last name for her and thats would be Guay ( spelling could be a little off). A believed birth year is 1902 to maybe 1906 . Any help or information would be greatly appreciated.
