I have received back my DNA test results which tells what percentage of each race I am as well as where within Europe my ancestors came from. I have also done a Y chromosome DNA test in order to find out the origin of the name "David" which is found a lot in the Czech community in Minnesota. I was very surprised to find myself with 6% Sub-Saharan African genes and can only assume that they came from the Czech (David) side of the family somehow. I'm looking for another Czech who can trace their ancestors to southern Bohemia (and preferably a David) who would be willing to take a DNA test to see if they also have African genes in them. Also interesting would be seeing the amount of Middle Eastern genes (as I have 5% there as well.) in the volunteer.
