Jean, >From Biographical Sketches I have read, there are reports of "seven " brothers who came over from Scotland by way of Ireland. My line goes back to a William that was born 25 Dec. 1725. He, I assume with his family, settled in Bucks Co., PA. He married a Sarah Mary Fleming and had 5 known children Does any of the above fit into your search ?? I think there is a confusion with duplication of names, also it seems Davisons and Davidsons are overlapping in facts. Any corrections or information is much appreciated. Lois S.W.
