On gedmatch.com I took my gedcom (family tree) file, looked for gedcom matches to my Tapp line, which has been proven native american, and search for others that had matches to my Tapp line. I found a gentleman who was linked to the early Taptico chief's, as I believed to be. Then, I took his DNA kit and compared it to mine. I found we had a small 7.3 centimorgan match on our 11th chromosome. I went back and looked at where the native american link was on my chromosomes and there it was the bottom 11th chromosome for us both, exact same place.
Now, this method is probably not the tried and true way of connecting methodically, but I like it because I got to play detective and have fun!
My 7th great grandfather, King Taptico (1664-1695) (Wicocomico Tribe)probable father Machywap (Chicacoan tribe) were part of this later Powhatan Empire. Man, did I have fun doing this!!
