I've just been in contact with Debbie D. I told her that I am interested in this line but haven't been working on it that much in recent years -- so my info is spotty on the far outreaching lines!
My grandfather Clifford was Killognaveen (and Doneen). His mothe was Sullivan from Lower Liss and Filmore. The family over there and in the US always tell me that the Bowlers are related to us. HOW???
My grandfather's Aunt lived in Fitchburg Mass. She had a brother Michael Sullivan that lived with cousins named O'Shea in Chicago. The Sheas are also very much related to us but HOW??? :-)
Hope we can piece together more info this coming year. Two heads (or thirty) are better than one!
