Kemp DNA

I'm looking for any male descendant of the Reuben Kemp 1754-1834 who has taken the YDNA test.The descendant must still have the surname of Kemp.Reuben Kemp was a Revolutionary War soldier with George Rogers Clark.He died in Crawford County, Indiana in the summer of 1834.I took the YDNA test three years ago and still have not found a match.I'd like to compare my test with another descendant of Reuben Kemp just to see how accurate my test was.
