This project started out as a Y-chromosome DNA test, meaning that only Griswold males could join the project. With the addition of the mtDNA test and the Family Finder test, the project is now open to all Griswold descendants, male or female.

The Y-DNA test is for males who carry the Griswold surname.
The mtDNA test is for males or females who have a Griswold ancestor anywhere in their lineage. If you trace your direct maternal lineage to a female Griswold, please let one of the administrators know this.
The Family Finder test is for males or females who have a Griswold ancestor anywhere in their lineage. If you have a brick wall on your Griswold line, this test may help you break through it.

We encourage all Griswolds, male or female, with any spelling variation, from any where in the world to participate.
