This page is a listing of some of the specific lines and origins from which participants are sought to the Coursey/DeCoursey DNA project. The lines listed here qualify for free and rebated Y-DNA tests. Lines marked "free test" will receive a free 37-marker test, the rest receive a $100 rebate on a test of at least 37 markers. First come first serve! To be eligible you must be a male carrying any variant of the Coursey/de Courcy surname whose direct unbroken male line (father's father's father, etc) fits one of the criteria listed below. If you qualify for a free or rebated test contact me before you order (courseydna "at" gmail.com).
The project is open to all males with any variation of the Coursey/de Courcy surname, so you are of course welcome to join even if your line isn't listed here. If you would like to have a line added to this list send me an email!
Examples of surname variations included in the project:
Coursey, Courcey, Courcy, Courci, Corsey, Course, Corse, Courson
DeCoursey, de Courcey, de Courcy, DeCorsey, DeCourcey, DeCourcy, DeCourse
The project has its own website here:
It contains the results so far and more information about the project and DNA testing.
The price of DNA testing can be a major deterrent to project participation. A testing fund has been set up in order to make it possible for individuals to participate that are either unable or unwilling to pay the full price. The fund offers rebates to prospective participants who belong to key lines. If you would like to help the DNA project recruit more participants by contributing to the testing fund, please contact me at: courseydna "at" gmail.com
