As my subject line indicates, I believe that all of the above-listed surnames track back to the Gaelic surname Ó Faoláin. Prior to the first Anglo-Norman invasion of Ireland in about 1170 the, Ua Faoláin, "Kings of the Deisi," controlled a territory roughly contiguous with modern County Waterford and a bit more. After the Anglo-Normans took over Waterford City and part of the County most of the old Gaelic families were pushed out over time. As a result the various Anglicized versions of the name (as shown above) began moving to adjacent counties so that by the mid 1800s they were about equally spread among Waterford, Kilkenny, Laois and Tipperary.
My family's first immigrant, Charles (I) Fallin is recorded as purchasing land in Northumberland County, Virginia in 1671. The fact that we fit within the old Ó Faoláin grouping was established a couple of years ago by a "67-Marker, yDNA" analysis done by FamilyTreeDNA. With all the varying spellings wandering around, yDNA analysis of a male with one of the listed surnames is, as a practical matter, the only way to positively tie up these, literally, ancient connections.
My family was likely one of the earliest of the group to reach America and I am particularly interested in contacting anyone who has a record going back past 1700, in America, Ireland, or anywhere else.
I have a reasonable grasp of the history of the family, much of which is somewhat controversial,
in Ireland prior to the Anglo-Norman invasion. I will do my best to answer any questions relating to the subject matter of this post.
