My great-grandparents are also Delia Grogan and William Flatley.(They were also from Ballyhaunis) I just checked our family bible records and William Flatley's parents were also Catherine Murphy and Michael Flatley. Delia Grogan's parents were Thomas Grogan and Nora Tarpey. My father,who is now deceased, grew up in the same house with Delia Grogan and William Flatley in St. Rita's parish in Chicago and has shared many stories about both of them with me. How is your husband related to Delia and William? Do you live in Chicago? I just stumbled on to this website and do not know anything about it so I don't know if you'll get this message directly or if you have to keep logging on to look for responses.
I would appreciate hearing from you if you have any additional information.
