My sister Margaret has done some research on John Grant of Lachine. If Simon Fraser is mentioned in with an Alexander Grant, it would be Hon Alexander Grant of L'Original. They would be first cousins. My 2nd Gr grandfather, Alpin Grant of South Branch in Charlottenburg, is another first cousin.
We have wondered at the connection to the John Grant of Duldreggan family and the Grants in Lachine. We think we know the relationship but still need the proof to say it is so.
