Edward, I would like to correspond with you on this. I'm pretty sure our spelling of surnames in the Louisburg area is the same (Kitterick). I was in Louisburg in April of this year trying to find documents or family from my branch of the Kittredge's. I have a copy of the Louisburg-Clinton connection that I got from Mary McNally in Clinton. Mary also has connections back to the Louisburg area and some possible family connections via the Kilcoyne's. While in Louisburg I spoke with the parish priest Martin Long about church records. Unfortunately the ones that I was looking for were earlier than 1850 and the church in Louisburg didn't have any prior to that date.
I took quite a few pictures of headstones in the "old" Kilgeever cemetery just outside of town. Many of my Kittredge relative still live in the Clinton area. I was interested in the Tierney's because my ggrandmother was a Tierney and I don't have any info about them other than her father's name was Timothy Tierney. Both were born in Ireland and my ggrandmother came over to Massachusetts but I don't know if her father or mother did.
I have a website that has as much family info that I have been able to find it is www.irishkittredge.com I would be happy to share any info / pictures that I have.
