The Casey Surname DNA Project

When traditional methods of research finally hit that "brick wall," Y-chromosome DNA testing may help in identifying new branches of your family tree. The CASEY Surname DNA Project, one of over 200 surname projects in the U. S., was created to take advantage of this new scientific approach, in an attempt to determine which CASEY family groups are related and have common ancestors.

Scientists have discovered that the DNA in the y-chromosome, found only in males, is passed from father to son, virtually unchanged, except for rare (and random) mutations. By testing these chromosome segments, it is possible to determine if two or more living males are related, and approximately when they had a common ancestor.

A New Year's gift from Robert Casey, delivered via the Rootsweb Casey mailing list:

We now have six Casey lines where DNA clearly establishes that these lines are connected in the last 200 to 300 years. Two lines from County, Kerry, two lines from County Limerick, one from County Cork and one from western South Carolina. I highly recommend that Casey researchers of southwestern counties of Ireland have their line tested with DNA submissions to determine how all these lines are connected. Of the seven lines tested with ties to southwestern Ireland, six lines have the same DNA fingerprint. One line in County Clare, Ireland is not related - but one line with late 1700s ties to South Carolina is related. Two branches have already emerged: Daniel Casey and Dennis Casey (of County Kerry) form one branch with markers 413A=21 and 444=13. Another branch found is Michael Casey (of County Limerick) and Daniel Casey (of County Cork) with marker 449=29. A very detailed updated analysis (two recent DNA submissions just added) can be found at my web site:

Found on the Rootsweb Casey mailing list, Clift Johnson has shared a great Casey family history that can be found on Ginni Swanton's web site.

Titled The O'Casey Clan: Their History, it was written by Sean O'Casey, Mullingar in 1950.

This information was written in the early 1950's and was provided by Cliff. Johnston, whose wife's maiden name was Casey.
This manuscript was found amongst her family's memorabilia.

I tested my DNA at the Ancestry website, but have not matched anyone. I hope you can help with your Casey lines you have tested. Is there anyway, I can use my DNA results with yours? Thanks for any help.

I was talking to my Uncle, and he says, that our family started out in Ireland with the family name Casey, but then our name was changed to Rogers. He said our family were in Quebec Canada before they ended up down in Louisiana. I wondered if maybe there was anything in Ireland's history that might account for the name change?

I know nothing of the Casey Heritage, where in Ireland my ancestors were. I am hoping to learn more.

Reposted from Robert Casey's 12/16 Email to the CASEY Rootsweb Email List:

I just updated my web site for the Casey DNA project. We now have 30 submissions and already finding out new information about all our lines with only 30 submissions. Here are some highlights:

www.rcasey.net/casdna.htm

1. Proved that Ambler Casey and Jesse E. Casey lines are a distinct branch (exact match at 67 markers with unique marker).

2. Proved that Ambler Casey and Jesse E. Casey lines are an genetic offshoot of the Abner Casey (mar. Elizabeth Bowen) line.

In the coming weeks, I'll be moving this web site to a new hosting provider. During that time it's likely that there will be some interruption in access to the site. Hopefully all will go smoothly with the migration, but being computers, there may be glitches, and I want just to re-assure all that this site will be back should there be any interruption in service.

When thinking 'Casey' and 'Baseball', it would not be unexpected for most people to think of the slugger for Mudville from the famous poem, Casey at the Bat. But there is another Casey in baseball, whose words are better known and are sung at most games, but whose identity has been lost in the unknown verses. She shares my daughter's name, Katie Casey. Here's how it goes:

Katie Casey was baseball mad,
Had the fever and had it bad;
Just to root for the home town crew,
ev'ry sou, Katie blew

On a Saturday, her young beau
Called to see if she'd like to go,
To see a show but Miss Katie said, "No,
I'll tell you waht you can do":

CHORUS:
Take me out to the ball game,
Take me out with the crowd
But me some peanuts and Crackerjack,
I don't care if I never get back,

Let me root, root, root for the home team,
If they don't win it's a shame
For it's one, two, three strikes you're out,
At the old ball game.

Katie Casey saw all the games,
Knew the players by their first names;
Told the umpire he was wrong,
all along, good and strong

When the score was just two to two,
Katie Casey knew just what to do,
Just to cheer up the boys she knew,
She made the gang sing this song:

I would like to make contact with all Caseys who are of the Irish Type III cluster.
see http://au.geocities.com/t120r61/index.htm
Of particular interest is the close connections of most of the Caseys on the phylogram chart.
The bulk form one group with a Hanvey showing his close relationship with this group, but there are two Caseys, while still part of the Irish Type III cluster, are quite seperate form the other Caseys.
