Part of the confusion may be that Wiki's project has very little to do with the General Society of Mayflower Descendants. That organization requires proof of lineage to the Mayflower Passengers. I think Wiki's purpose is really just if you have an interest in them. There are many Mayflower descendants who have never proven their descent with the GSMD, but they are still descendants. Many others who are collaterally related, and still have great interest. Anyone can be interested, no matter what their ancestry, and should be encouraged if they can help.
