My wife's great-grandmother was Catherine Brown (born 1841), the daughter of Donald Brown (postman) and his wife Mary (ms McKinlay). She was one of 11 children. I think Donald Brown. with his wife and family, lived at a cottage near Torrisdale Bay. Her younger sister Margaret (born 1843), who married Neil MacDougall, was the great-grandmother of Neil ('Dona') MacDougall who lives at 'Duncrannag', Carradale.
My wife's father was Dr James Dunn (1918-2011) whose mother was Isabella Dunn (ms Blackburn), the daughter of Catherine Brown. The family used to spend their summer holidays in Duncrannag in the 1950s and 1960s. We met up with Dona at a recent visit to Carradale.
If anyone can fill in any background to the families, that would be great!
