So does need to be a male with the last name of Hayden for the testing to be valid? My tie to Hayden is: Julia Hayden (the daughter of Nehemiah that I have on the web site) Her son Otis Dickey His daughter Julia Dickey (My grandmother) Her daughter Donna Pratt (My mother). So if I or my mother were tested would it help the project any?

Sorry, Ernie. The test measures markers on the Y-chromosome. Only males have the Y-chromosome so it is passed from father to son. Your Y-chromosome is that of your father, his father and so on back. In your case, you would need to find a Hayden male descendant of Nehemiah. The surname does not have to be Hayden but unless there is a link, such as a name change, assuming a common male ancestor can be risky. For example, one of the descendants of William Hayden of CT in the project has the surname Keys. The test confirmed that this subject did descend from William Hayden as was believed based on research.
