Hello Alex
"Is your Murray Babington the chap who married Mary Heron Gordon..."
Yes, that is the one, although I did not know the marriage actually took place in Dumfries, Scotland but that does stand to reason given that Mary Heron Gordon's father was from that part of Scotland. Interestingly, I have Mary Heron Gordon's mother as a "Margaret Stewart" but know nothing of her antecedents nor of any connection to the other Stewarts on my father's side.
Murray and Mary had three daughters, as I understand, and I trace my descent from Patricia Babington.
