We have a whole line of Devlins', decendents of Dennis and Margeret Devlin. Came from Irland (we think) to Boston, Mass in Aug 1846. I am wondering if he could possibly be a brother to Patrick.I keep running across the info that Patrick may have had two siblings, but no one seems to know thier names.We have no info on family of Dennis before arrival in states. This seems to be the closest match I can find. He had four children.Micheal,Mary,Susie and Hannah.Micheal is my ggrandfather. If you have anything please reply.
