so my family is from Rathlin Island, I have cousins all over now but in the mid to late 1800s were in Maine and Boston area. I have recently seen lots of stuff from Antrim county, numbers of families of catholic and prot religions. I have a few Kat(Catherine) even Kitty Wilkinsoin/Mcquilkin aunts and cousins, my 4th ggrandma was a Margaret but thats a very common name.
I know of a couple of sites tha thave large data base for Raghery people.
