You can purchase an 8-generation CD from the Alden Kindred of America, Inc., at http://www.alden.org/giftshop/cd_info.html. This CD contains the gedcom of the entire AKA 8-generation project including sources and much additional information. The information was taken from the Alden silver books, the Mayflower Descendant, Susan Roser's books, vital records, and membership application papers, plus more. Most, if not all, of this information has been thoroughly documented and is entirely reliable.
