Hi Gerry,
It is a small world - my husband and father have both had procedures done by your cardiologist brother, Jim Tierney!
Your latest info from the Heritage Center in Cavan is sure to proof to our relationship! The bapismal sponsors for my father and his brothers and sisters were all aunts and uncles, so it is likely that my grandfather, Francis would be a sponsor for your grandmother, Anne McEnery. If this is the case, my father James and your grandfather would be first cousins and I would be a second cousin to your father. What is your grandfather and fathers names and who did they marry? I am curious to know what brought your great-grandfather to St. Paul. Was he a farmer like his brothers? Do you know when he came to America and if he went directly to your area? Let me know what more you learn from the Heritage Center. Thanks for all your help in my search for answers!
