I'd like to help with this project. I'm relatively new to WikiTree, and could only provide one week a month to dedicated help. According to the one tree, 33 of the Presidents are cousins, the other 12 related through marriage. With the surname Grant, I am 17 generations from US Grant. Living in Cincinnati, this could be an option. I'm actually closer gen-wise to Hayes, Fillmore & Adams (2nd) - 15 gen. & Adams (6th), Garfield - 16 gen. My location might work with Taft - 20 gen. The topic of Presidents has been a hobby of mine for over 60 years. I'm open to suggestions.
