I'd be interested in exchanging information regarding an entirely separate Patrick Duffy/Phillip Clark lineage. County Tyrone(Duffy) to upstate NY about 1850s and Clark(County Cavan) to Boston about 1837 and then onto upstate NY. Clinton and Ellenburgh County in NY. Phillip Henry Clark and Sarah Jane Duffy Clark(daughter of Patrick Duffy and Catherine Monaghan Duffy) are my GG Grandparents. Kelly Clark mizkmc01@hotmail.com
