SNP Chart
The chart tabulates Corca Laidhe surnames listed on our FTDNA Background page by their SNPs we know of to date. The chart will continually be updated as members choose to actively participate and to acquire SNP data.
Our primary anchor region is defined as County Cork and County Kerry. We are basing this on "Ireland's History in Maps" by Dennis Walsh, on Rootsweb. [At some point we will develop our own maps.] We think we know the following: Corca Laidhe rulers briefly ruled over most of Kilkenny; after the CL rulers left, there was still an ecclesiastical relationship between Cork and Kilkenny that persisted due to the efforts of St. Kieran; priests and possibly their extended families moved when they relocated to fulfill their assignments; Irish probably migrated around the island after major battles / events. Therefore our secondary anchor region is comprised of Kilkenny, south to Waterford, then westwards across Tipperary, and Limerick. Although the diocese of Ossory, associated with Kilkenny, nicked a corner of County Leix (Louth, formerly Queens), we will leave that out for now. We will also leave out County Clare, though we will keep in mind that Cromwell may have dislocated many relevant people from Northeast Munster northwest into Clare. So our anchor region for now is comprised of Munster minus Clare, plus Kilkenny. The anchor regions combined are what we'll call the region of influence.
The chart splits project members with known ancestry from the anchor regions from other members with known ancestry from outside the region. This is an ongoing experiment, just a starting point to see where it leads. Known ancestry from the anchor region does not necessarily prove Corca Laidhe ancestry, nor does known ancestry from elsewhere necessarily disprove it.
Opinions on distributions of surnames in Ireland are based on Griffith's Valuation and the 1901 census. These sources do not necessarily reflect the distribution of surnames from the 11th and 12th centuries. As already mentioned, the Irish likely migrated after major battles / events, and more recently migrated for major work opportunities, to such destinations as Belfast and Dublin. After each major encroachment on Corca Laidhe territory, at least some of the inhabitants of the area undoubtedly left / fled for safer pastures.
Opinions on the distributions of SNPs are based far more on conjecture, though we have sources such as YFull.

Haplotrees
If you need help with any of the terminology here, the DNA tutorial researched and authored mostly by the project administrator, particularly Parts 3 and 4, might be of some help.
These haplotrees integrate ISOGG, FTDNA, YFull and Big Tree data. From ISOGG we get SNP long forms. From either YFull or Big Tree we try to obtain approximate TMRCA data.
Unfortunately, these sources of information are not in sync with each other. It is usually the case that one source will be more current on a particular SNP branch than the others. Therefore, expect data on this page to be inconsistent and contradictory, and maybe out of date by the time you look at it.
Where ISOGG only has partial long form data, dots (.) or question marks (?) are used to fill in the missing slots.
The rows of certain key SNPs may be shown in bold to serve as roadsigns.
The names and known ancestral origins of study participants, or other notable pieces of information, are in bold with a blue background.
Our haplotrees only diagrams the results of project participants with patriline ancestry within the Corca Laidhe region of influence.
