My GG Grandfather, Lawrence Duffy married Rose ??? In 1872 at St. Macartan's Cathedral in Monaghan. They had 22 kids. One was John who lived in Tanderagee in Monaghan Co. He married Catherine McPhillips and had 6 kids: Vincent (was a priest in NJ who recently passed), Lawrence, Kathleen (Kay), Emmitt and my grandfather John Albert.
If you know any details of this family line I would love to hear from you. I am planning a trip to Monaghan in 2012 and would like to find my relatives.
