I may be able to help answer someof your questions. I am including below the lineage From William Brewster to Seth Hinckley. William Brewster is the only Pilgrim I have been able to link to the Hinckley’s.This link is already proven to the Society, in fact they have 9 generations proven. You can go to http://www.mayflowersociety.org/http://www.mayflowersociety.org/and find the form to fill out for verification of your lineage. By proving I mean marriage, death, birth certificates, from you to whoever they have on record.
I have other information on the early Hinckley line, but the conversationwas Seth and Mayflower. If I can be of more help, please send me your questions. I do not have all the information of all the branches but might be able to help some.
