New Mayflower Society DNA policy on their web site now

 The official policy is now online. To find out what it takes to join the Mayflower Society using DNA evidence, go to the GSMD site and near the top, on the right, hover over the word "Join" and then click on "Resources." Then click on "GSMD DNA policy" and a file will download to your computer. Though I did not see mention of specific DNA test providers it is clear that you MUST use one that reports 37 markers - at the least - and gives you a report that is essentially a string of 37 (or more) numbers and states which genetic haplogroup you belong to. The ads you see on TV in which people announce that they "just found out" they are part Irish or part Native American or part Whatever are not adequate if that is all they say. Neither are the reports that say you are "5th cousin" to So-and-So Famous Person. The numbers tell the story with DNA tests, not a cute graphic. You must also prove the entire rest of the lineage the traditional way (with vital records & other official documents) and have only the one point in question. You must get some other male who has already joined on that line to take the test, and then you take the test if you are a male. If you are female you must get a very close male relative (brother, father) to take the test and then document their relationship to you. So, if your application is in Limbo over one sticking point that you think could be resolved by a male (Y) DNA test, check this out. Be aware that you are asking to join someone else's association. You do not get to substitute some other test or do something different because it is easier or cheaper for you. You must follow the organization's instructions (which are the result of nearly a decade's research.) If you have any questions, ask the GSMD first.
