I am shocked. I don't think I've ever seen anyone who has heard of Marion Howell!!!! I've been asking about her for years.
My records say that Duncan was born in 1804 and married in 1821, but I don't really know anything about those years. How did you get the Feb 6 date??? Do you know anything else about her? I'd about convinced myself that Marion was a ghost.
I come into the line via his daughter Catherine 1842-1895. I'd love to hear about anything you know and will be happy to share what I have.
