Ancestral Family Tree DNA Testing / Charting of Irish haplogroup R-L226 is now 90 %
« on: Tuesday 03 July 18 08:26 BST (UK)  »
There are three major haplogroups that are found dominated by Irish testers: R-M222, R-L226 and R-CTS4466. Between five and ten percent of all Irish people descend from these three haplogroups. Also, these three haplogroups have between 500 and 1,000 branches under these as well due to being such prolific lines. L226 and CTS4466 are from the Munster, Ireland while M222 is located in the central and northern parts of Ireland.

Here is a chart that shows how over 600 L226 are connected to each other. L226 starts around 1,500 years ago from County Clare and includes the line of King Brian Boru (this page includes my Casey surname cluster):

United States of America / Caseys living in South Carolina (1750 to 1800)
« on: Friday 14 July 17 21:36 BST (UK)  »
We have long believed that the majority of Casey men living in the South descend from early Casey ancestors that arrived in the early 1750s. Based on the 1960s manuscript by George and Abner Casey, these men were connected to early Casey men in Virginia. There are around 50 male Casey men in South Carolina by 1800 (mostly in Spartanburg County, SC and the rest in nearby counties). The ancestor of all of these men has been stated to be Abner Casey and his wife Harriet Green but no primary documentation has been found to date on this man or his wife.

Since I could not make any progress with all the source documents found in South Carolina over the last 40 years, I decided to become the admin of the Casey FTDNA project in hopes of breaking through this brick wall. Here is where we stand after ten years:

1) Around 25 Casey YDNA testers who have ties to early South Carolina (or believed they have ties to early South Carolina) have tested to be very closely related in the last 200 to 400 years. There is only one exception - Elisha Casey is related only around 1,400 years ago - too early to share a common Casey ancestor.

2) Anyone who tests positive for the YSNP branch, FGC5639 are all descendants of a common Casey male ancestor in the last 300 or 400 years as we expected. There are only two confirmed men with much older connections (500 to 700 years) that are connected to this surname cluster. Since there is little YSTR variation between these testers but a huge variation from haplogroup L226 YSTR signature, this line is very closely related in time frame of the colonization of early America.

3) For the two older lines, one very big surprise is a Kersey tester who has his line traced back to the early 1600s in Oxford, England (it is believed that this early Casey line moved from Ireland to England and changed their name to the English Kersey surname to hide his Irish heritage). During the last week, we discovered our first Casey line from Virginia and North Carolina in the 1700s. Both of these lines are FGC5647 positive and FGC5639 negative. Both of these lines probably much older than the colonization of America but have a common Irish Casey ancestor around 500 to 700 years ago.

4) The next closest YSTR matches are several "Carey" testers. These connections are a few hundred years earlier than the Kersey and the older Casey tester. It is believed that they share a common ancestor between 700 and 1,100 years ago. It is not certain if the share a common Casey or Carey ancestor - but similarity of surname is very interesting.

5) We are very lucky to have a major YSTR branch 460 (11>12) which pretty much divides all of these Casey lines into two branches. We believe that this branch happened around 1650 to 1750.

Unfortunately, we do not have any Casey men who reside in Ireland today that are related to this South Carolina cluster of testers. The entire Casey project only has five Casey men that are tested from current residents of Ireland. None have tested or are predicted to be related to this very large Casey genetic cluster in early South Carolina:

535407 is from County Sligo and has tested I-Y5451
5702 is from County Tipperary and has tested DC69 (branch under R-L226)
129039 is from County Cork - only tested for 12 markers
260341 from County Limerick - R-M269 (but not R-L226)
484828 is from County Cork - I-P37

6) Of the 83 known testers with the Casey surname, 30 % currently belong to the South Carolina cluster. It is believed that around 25 % of all Caseys in the world are related to this one genetic cluster that share a common Casey ancestor.

If you are Casey descendant of any Casey line that you believe has ties to early South Carolina (those that descend from the speculative Abner Casey and Harriet Green), it is highly recommend that you have your 67 markers tested at FTDNA and join the Casey FTDNA project.

If you are a Casey descendant that currently resides in Ireland and who can trace their Casey ancestry back to the following Irish counties: Clare, Tipperary, Cork, Kerry and Limerick (to at least a birth before 1870), I will sponsor your 37 marker test at FTDNA as long as you agree to continue us to allow testing your YDNA if turns out to be a significant discovery.

Ancestral Family Tree DNA Testing / Casey YDNA project
« on: Monday 26 June 17 15:21 BST (UK)  »
This thread has a lot of references to the surname Casey. I am the FTDNA administrator for the Casey YDNA project and one of the co-admins for the R-L226 Haplogroup project (the second largest Irish haplogroup with 540 testers at 67 markers). My Casey line and two others (who do not share a common Casey ancestor) are also R-L226. Around 25 % of the the 75 Casey YDNA testers are R-L226 with the remaining members spread across many other haplogroups that can not share a common Casey ancestor (well over 1,000 years old).

Where we know the Irish county of origin, 80 % of the R-L226 testers are from the following Irish counties: Tipperrary, Clare, Cork, Kerry and Limerick. 10 % are from other Irish counties and the last 10 % are from many other countries (mainly England). We know that this haplogroup is of Dal gCais in origin as the surnames align very well with the Dal gCais and Sir Conor O'Brien (title holder of the O'Brien surname) has tested R-L226 positive.

My particular Casey line first appears in United States in the early 1750s in western South Carolina. Speculation was that the South Carolina line was connected to another Casey line in Virginia - but to date, several of the Virginia Casey lines have been YDNA tested (where Ancestry.com states they are connected to the South Carolina line). Unfortunately, YDNA continues to disprove these connections due to non-matching YDNA (no common ancestor in the last 4,000 years). The only European in this cluster that matches this Casey cluster is a Kersey who traces his line back to Oxford, England in the early 1600s. We suspect that this person was originally a Casey (due to sharing a very unique YSTR signature and very recent YSNP branch) but changed his surname to the English surname Kersey to hide his Irish ancestry.

We have 75 YDNA testers for Casey men, unfortunately we do not have a single Casey tester that currently resides in Ireland today. We do know that South Carolina Caseys were very prolific and by 1800, there were around 50 adult Casey males in South Carolina). This branch of the Caseys probably represent 25 % of all Caseys in the world today. Recent Social Security records indicate around 50,000 with the surname of Casey (this includes women). Many children are not included unless they have entered the work force to pay Social Security taxes. My father and I published a "Casey Family History" book in 1980 and I have greatly expanded this publication to include several of the major South Carolina lines that I believed to be related.

If you have a male Casey ancestor that are well proven back to the 1870s and still reside in Ireland today in the five Munster, Ireland counties listed above, I will sponsor (pay for) a 37 marker test at FTDNA ($139 value). The only other requirement is that if you turn out to connected to one of the major Casey lines in the United States, is that you would allow additional extensive testing to determine your exact relationship. It would also be preferred if the tester also upgrade to 67 markers if you match one of the major Casey lines (cost of $99). If you match the South Carolina cluster of Caseys, our project would probably sponsor a Big Y test ($575) or a Whole Genome Sequencing test ($775). Feel free to email me, mail me or call me at contact method of your choice:

Immigrants & Emigrants - General / Casey immigrants to South Carolina from Munster, Ireland in the 1750s
« on: Thursday 04 May 17 00:26 BST (UK)  »
I have been compiling various Casey families that started arriving in western South Carolina in the early 1750s. Poorly documented tradition originally stated that these lines moved south from Virginia where earlier Casey families resided. However, genetic testing has all but eliminated these lines as being related to the South Carolina lines.

I am the administrator for the Casey FTDNA YDNA project which has around 175 testers (around half list their oldest proven ancestor as Casey). To date, we do not have a single Casey tester who currently resides in Ireland today. There are two very large Casey clusters that account for almost 50 % of all Caseys that have tested to date. These two clusters have tested positive for R-L226 which is the second largest Irish haplogroup with Irish origins. This haplogroup is dominated by Dal gCais surnames and for all L226 testers who list their origins by county, 80 % are listed in only five Irish counties (Tipperrary, Clare, Limerick, Cork and Kerry).

In order to encourage testing of our Irish Casey cousins that still reside in Ireland today, I willing to sponsor a 37 marker test (pay for - value $139). You only have to have your all male Casey line traced back to at least 1860 to one of the five counties listed above. With the 37 marker test, we can quickly determine if your results are part of the L226 haplogroup. If you do turn out to be L226 positive, you also have to allow additional testing as required (upgrades to 67 markers, taking of the L226 SNP pack and Big Y testing). If interested, please send me an email for more details:

Ancestral Family Tree DNA Testing / Looking for Casey volunteers to test their YDNA - free test
« on: Sunday 12 March 17 16:53 GMT (UK)  »
Hi - I am the admin of the FTDNA Casey YDNA project which now has around 160 members and around 80 Casey men that tested to date. However, to date, we do not have one Casey tester who currently resides in Ireland. We have many Casey men in the United States that have traced their ancestry to Ireland. All of these Casey lines came to America during the potato famines of the mid 1800s. I belong to the Casey line that left Ireland during the massive crop failures of the 1740s and were residing in western South Carolina by the early 1750s.

I am seeking volunteers to join our project so that we make connections between our common Casey lines. All of our distant Casey cousins that we known must originated somewhere in Ireland. Almost half originated in Munster, Ireland. Last November, I traveled to Ireland for the first time where I gave a presentation on YDNA research at the Genetic Genealogy Ireland conference in Ireland. At this conference, I was given one 37 YSTR test ($139 value) which I would like to sponsor a Casey genealogist in Ireland. My intent was to give this kit away when I traveled down Munster but quickly became of tourist of the very historic Ireland. I will sponsor one test with the following conditions:

1) My Casey line is definitely Dal Cais since I have tested R-L226 which is one the three major Irish YDNA haplogrops, so I am only interested sponsoring the test for the Casey lines that originate in Munster, Ireland (specially the counties of Tipperary, Limerick, Clare, Kerry and Cork).
2) Since this is YDNA test, you must male descendant with the Casey surname with no known adoptions in your Casey ancestry.
3) To maximize the impact of the test, I will need somebody who has traced their line prior to 1850 for their Casey ancestry. I will need a list of your all male Casey line, so it may be added to Casey Family lines at my Casey DNA web site.
4) Although it is not a requirement, it is desirable to have the test upgraded to 67 for $99.

Here is link to a chart that summarizes the South Carolina line (and charts 80 % of all known L226 testers at 67 markers):

http://www.rcasey.net/DNA/R_L226/Haplotrees/L226_Home.pdf#Page=26

Please note that 44 % of the Casey men that have tested to date are YSNP tested for R-L226. This is one of three known major YSNP branches of mankind that are 90 % Irish in origin. R-L226 has surnames that dominated by Dal Cais surnames 80 % of the 520 members of R-L226 have ties to the above counties listed (when their oldest proven ancestor is traced back to Ireland).
