Determine main lines of Floyds/Floods/Floids. If you are a male of Floyd/Flood/Floid descent (your last name is Floyd/Flood/Floid) you are a prime candidate. If your surname is not the above or you are female, consider having a male Floyd/Flood/Floid relative of your line take the test as your representative.We currently recommend a Y-DNA Test of at least 37 markers be taken and results submitted to aid the project's research efforts. We are actively looking for a volunteer co-administrator to assist in the administration of the project.. If you are interested, please contact the admin
