All BRIDWELLS are encouraged to participate in the BRIDWELL DNA project. Male BRIDWELLS may participate directly. Because females do not have the Y-chromosome they can only participate through a male BRIDWELL relative (father, grandfather, brother, uncle, cousin). You may choose either the 12, 25, 37, or 67-marker test. Test results will be returned to the Family Coordinator as they are received by FamilyTreeDNA. Each participant will also receive a certificate and report containing their personal test results. Remember, the test does not involve giving blood sample, it only involves swiping the inside of your mouth. Thank you for participating..
