About us

The Hollow DNA Project welcomes all participants. If your surname is Hollow, Hallow, Hallo, Holla or Hollah we encourage you to join the project.

Our project currently has ten participants and already we have some interesting results. The more participants we have the more we can discover about our families.

Participating is an opportunity to uncover information not provided in the paper records, which will help with your family history research. We will also discover which family trees are related. As the project progresses, the results for the various family trees will provide information about the evolution of the surname.

The surnames in this DNA Project are researched as part of the Hollow One-name Study. You can learn more about this significant research, and the the associated family trees, by visiting the one-name study web site, or contacting the Project Administrator.

The Y DNA test tells you about your direct male line, which would be your father, his father, and back in time. You must be male to take this test, and you should have one of the surnames shown.
If you believe there is a Hollow or variant in your direct male line, although you have a different surname, you are also welcome to participate but first contact the Colin Hollow.
If you are female, you will need to find a direct line male in your family tree to participate and represent your tree.

We encourage males to order a Y-DNA test for 37 markers, if possible. If you order less markers, you can upgrade later, though this costs a little more.

The Y DNA test results contain no personal information, and you will match or be a close match to those to whom you are related. This is an opportunity to learn more about your origins and ancestry.
