I'd be interested in sharing information, since I don't have anything on your branch of the Churchill family after Arthur Churchill. I've since revised my view that there was this Joseph Churchill, born 1779, was the patriarch of my branch of the clan. More likely is that a James Churchill was our common ancestor. Anyways, I'd be interested in the Arthur Churchill line, and I can let you have my stuff on the family as well as a short paper I'm trying to finalize sorting out the Churchills of Ontario, who are very confusing thanks to the fact that they shared so few Christian names. Let me have your private email and I'll send you the material
