The General Society of Mayflower Descendants has published a series of genealogical books that trace the first four to six generations of descendants for each Mayflower passenger; new volumes regularly become available as the Five Generations project of the Society progresses. These books are noted for being very well documented, highly accurate, and are the best quality genealogy on Mayflower families available today. Books range from 200 to over 700 pages; most are $20 or $25, but some of the larger volumes are $45-$60. Click on the volume of interest to see pricing information and to order them from Amazon.com. Not all are always available from Amazon.com, and sometimes the third-party sellers only offer an exorbitant price. If they are not available or are being sold for an unreasonable cost, you can also order them directly from the publisher, the Mayflower Society.
