The Hill DNA Project:
Every male Hill should get a Y-DNA test and submit the data to this site. If you don't already know your ancestry or if you have hit a "brick wall" then you may find a clue that will help your research. If you already know your Hill ancestry as far back as you want to go, and you publish your ancestry, then your Y-DNA may help someone else in their research.
