I might have a little bit of info for you. I just found out that my G- grandmother was a Judy Qualter. My best guess is that she was born in the mid 1800s. She was married to Peter Greaney. They had 4 children grow to adulthood and they lived in Cahirmorris, Co. Galway. He was a landowner-?-
My Grandmother was a Bridget Coen from Cappagh ( near Newbridge), Co. Galway. Her father was Martin Coen and her mother was Julia Mcloughlin. He was a laborer. My grandmother had 2 sisters and 2 brothers .All the girls emigrated to NY . One brother went to England and the other stayed in Ireland.
