Hello cousins Gateslack and catchristie!
I am descended from James Maxwell b 1779, son of John Maxwell born about 1747, son of William Maxwell of Milton and Janet McLellan of Auchlane. So my John is the brother of Grizel who married William Rae.
I am hoping that you can tell me how you know that Grizel is the daughter of William and Janet. I don't have any documentation of John's birth and hope you might have done some more successful research in that direction than I have.
My information came first from the memorial inscriptions at Durisdeer churchyard, which were very helpful, but do not go back to William and Janet (as far as I know).
