Marc, The Mayflower Society requires "demanding" proof that you are a descendant form the passenger listed. This is to discourage the many who are not actually qualified. however, the "proof" may be left up to those who oversee the application. (sometimes, a birth certificate is not available, but a will, deed, etc., will suffice). You may also wish to contact the Sons and Daughters of Pilgrims. L. Toussant
