The Clements Surname DNA Project is open to any male Clements/Clemmons etc who would like to join. We have participants representing the Y DNA pattern of most of the early American immigrant Clements/Clemmons ancestries to help you determine which line you match. Please see our website for more specific ancestor information. You have 46 chromosomes. Only the Y (one out of 46) is tested. This test cannot identify you. It can only identify your ancestral line.
