This does sound like the same family. Our family comes from William Egan, son of Kieran & Julia Egan. Perhaps William & your father, Michael Egan, were brothers? I would love to see what other information you have. I have information from a relative here in the US that lives in New Jersey, but has visited Birr many times and knows many relatives. Do you have any information on other children of Kieran & Julia and of the parents of Kieran Egan or Julia Dooley/Dooly. I have seen it spelled both ways. Thank you so much.
