Hello
I found this thread that may be of interest to you.

Can either of you provide a link about Farquhar Bethune and Charotte Lelond 12 children? I am a descendant of Farquhar also, but I need to fill the gap from Farquhar to Donald Beaton of Isle of Skye. From there can go to the present. From Farquhar up, I I go back as far as Robert Bethune and Janet Balfour. I just need the middle part.
