little late replying. One thing I found doing Guinan genealogy, the section of Ireland (So. Roscommon) where cluster of Guinans lived, had many Dolans, Egans, Naughtons, Kellys, many of whom still live there. It's difficult because the area of Tipperary/Offaly/Roscommon/Galway are not far from each other, but I found info in Athlone. Don't have as much time as I used to with digging, but I'll keep this in mind as I'm spending more time on the Boston area genealogy now.
