Thanks for your reply. Very little is known about Mary Balfour's family, and her own life is hazy. I'll be glad to send you what I have. I think her father was a John B. who was a doctor but became a clergyman in Derry, but there was also a William Balfour who was a doctor and definitely had a daughter Mary. Are you related to the gentry family of Balfours of Townley Hall, Louth, Ireland who descend from a Fifeshire family? Please keep in touch! All good wishes Linde L.
