It's funny I actually already had Richard William Davis and Mary Craigie in my tree, but I hadn't made the connection between these two Mary Craigie's now.
Mary and Richard's daughter, Jane Davis was the 2nd wife of Andrew Nicholson whose first wife was Sarah Foulis, that daughter of my James and Elizabeth (Craigie) Foulis. Unfortunately Sarah died shortly after their marriage due to complications from a miscarriage.
Nice to hear from people I am related to. Thank you very much for helping me with that, even though you didn't mean to.
