My Husband is 100% Scots-Irish according to his DNA results, with 87% being Irish. (I do all the research for both of us.) Most of his ancestors came to North America in the 19th century, many settling in Newfoundland, Canada and Massachusetts, USA. A few went to Australia & New Zealand. His great grandmother was born in Glasgow, Scotland. His Irish roots come from Munster: Cork & Waterford, Wexford, Wicklow, Mayo and others. Also from Galway, Dublin, Carlow, Louth and others. I was so surprised that there was no other indication of any other DNA showing up! Does that happen often? It seems that even after his ancestors left Ireland they, for the most part, continued to marry only other Irish. Some left Ireland to work in the woolen mills in England for a time before coming to Massachusetts but they still married only other Irishmen. It's only our generation, (we're both in our 70's), that other nationalities start showing up in my husbands tree. It seems as if they would only marry other Irishmen. I realize that Ireland is an Island and not many outsiders would want to settle there but there had to be some (I'm referring to 200 plus years ago) Am I the only one that thinks this is unique/strange? I haven't seen any of his DNA matches that have this genetic make-up, even his cousins have a broad mix of ancestors.
