Yes, the Tipswords from Decatur and Bethany are direct descendents of Griffin, as are all Tipswords. All Tipswords descend from Griffin through his sons John, Isaac, and Thomas. As for the Kickapoo heritage story?? I do know Griffin gave his oldest son Andrew to the Kickapoo to raise as their own, in a friendship jesture. Gayle Tipsword Norris has the greatest knowledge of the Tipswords and Griffin. Her name and e-mail are posted in this site. I hope this has helped.
