The General Society of Mayflower Descendants meticulously investigates primary records that substantiate the identity of individuals and families that descend from the Pilgrims who traveled on the ship Mayflower in 1620.
The pink 'Mayflower Families in Progress' (MFIP) booklets are silver books in the making. These booklets are made available while new information is being researched. Once complete, they become silver books. GSMD makes them available in soft-cover so that the information can be available to genealogists while further research is underway.
