As I do further research, such as Chronicles from the book, The Last Highlander by Sarah Fraser, and other Fraser History, I am no longer sure if Simon Fraser, 11th Lord Lovat, had 3 or 4 wife's or how many children each had. I am pretty sure that his last son Archibald was from his last wife and that Simon and Alexander were of Margaret Grant Fraser, with 3 daughters being born prior to Simon.
