Thanks Elwyn.
My ancestor , Jeremiah Moore, was born between 1800 and 1810, if you can trust the one census he appears on, and left Ireland prior to 1838. I have checked various sources civil, Methodist and Church of Ireland without any results. I attended two of the British Institute classes on Irish Genealogy in Salt Lake City to get help and advice. I even get copies of draft papers from an accademic who researches early Cork in hopes of finding my ancestors. I have found quite a bit on genetic cousins, but both trees hit a wall about the same period. When ever a new source comes on-line or to my attention, I also check on the Moher surname as one of those families is a Y-DNA match. The Mohers were and are Roman Catholic so I also check those records, just in case. atDNA confirms that my Jeremiah was associated with a group of Methodist families who live in an area from Schull in the south, Ballydehob, Skibbereen, with a significant number in Clonakilty area, Kilgarriff Parish. The same surnames and people keep appearing in these genetic cousins trees: Ballard, Beamish, Bennett, Cole, Connell, Copithorne, Dickey, Evans, Fenwich, Gardiner, Hadden, Jermyn, Justice, Lanktree, Levis, Moore, Morgan, Newman, Richey, Ross, Roycroft/Raycraft/Reycraft, Skuce/Skuce, Swanton, Sweetnam/Sweetman, Vickery, Warner, Whittey, Willis, Wilson, Wolfe, Woods, Wright. (the bolded ones are the most frequently occurring.) Because they married within their faith, the atDNA relationships are predicted at a closer level than is possible based on the paper trail.
The Moher family is up near Kilworth, north of he City of Cork, and the connection is farther back. So far there have been no atDNA links between the Moore family and the Moher family of Kilworth.
