An Avent DNA testing project has been set up, and several of us have been tested, with interesting results. Rather than go into them here, you can see them at my website,
www.aventfamily.org. Look for the link to 'Avent DNA Studies'.
One interesting result, so far, is that it has proven that it is very likely that the Avance family, of Anderson Co., TN, is descended from Col. Thomas Avent of VA (1671-1757).
