A male, Tighe relative of mine is the first one to sign up for the Tighe DNA testing. If you are interested, please go to http://www.familytreedna.comhttp://www.familytreedna.com and click on the Surname Projects on left hand side of page, go to the T section and click on the TIGHE group.
You have to be a male with that specific surname to do the DNA testing. Women do not have the Y chromosome that they test for. So, for example, if you are a male with the surname McTighe you can sign up on the Tighe surname page.
We thought it would be best to include the McTighe and O'Tighe surname as well to see if there are any blood connections.
I am the administrator for the Tighe group so I get periodic updates from the Family Tree DNA site when someone joins, etc.
