Are you ready for this? I am the 13th great grandchild of someone who was the 3rd great grandmother of Pres. Washington...? WTF? it seems my mom is the 4th cousin 9th removed of Pres Washington. Does that make me 4th 10x removed? She has the tree but I'm not a subscriber of ancestry.com so I cant see it. I recon there are over 8,200 people related just going back 13 generations if everyone had 2 kids....It seems a cousin is any offspring of an aunt or uncle no matter how far they go back (ie great great great grandmothers sisters kid is your cousin). 9th removed is how many generations it goes back?
