Finding family origins and new cousins are two benefits of participation in the Harden.in.ing yDNA Project. All males who have the HARDEN, HARDIN or HARDING surnames (or variants) are invited to join the project. If you're researching these families and want to learn more about your Harden.in.ing ancestors, please urge an eligible male in your family to participate. The goal is to find common ancestors & establish the genetic connections among the various families through Y-Chromosome DNA test results.
