Hi David Its a long time since you posted your message however I hope you still log in occasionally. I am related to Williams brother John, he is my GGGGrandfather b.Ratho 28.7.1811. Both he and his wife Ann were living in Long Dalmahoy in 1881, his employment is given as road contractor. I believe there is a link to the canal at Ratho. Have you progressed any with James and Margaret Baxter? Do you want to exchange information? Good luck anyway.
