Hi, Jackie! I'm the group coordinator for the HOLDER DNA project at Family Tree DNA, and I have a lot of information on John Holder of Kentucky, as well as many other Holder lines. Among other aspects of this projects, I have been systematically going through the Holder profiles on WikiTree, creating links and making comments where I can add information. Please contact me at ncgen@mindspring.com and let's talk further about your Holders. Elizabeth (Holder) Harris.
