Hi, My mother is Dorgan and is from Carrignavar. I am trying to do a family tree and I have traced back to a Denis Dorgan born abt 1780 but I have no info on him or his relations.I know of a book by Jane Dorgan which might be of some help but I do not believe there is an online copy.Would you know of any resources for Dorgans of Carrignavar or how to get that book?Thank You Michael Cronin
