Silver - published "final" version. -- Until it is revised. Pink - in progress books. Published as an interim to the silver versions. It is recognized for Mayflower purposes, but not everything in it is in final form or they are still working on some of the lines before going silver. Green - not a Mayflower passenger - only one published so far and that is Delano. This family ties into Mayflower. White - This one someone else is going to have to answer. I was going to say not a Mayflower passenger, but I have a Francis Cooke - who is Mayflower and William Bradford is too. But Robert Bartlett was not, only had children who married Mayflower passengers children. Cushman - Has fall foliage colors on the cover. Thomas Cushman married Isaac Allerton's daughter and many of their children interact with lots of Mayflower descendants. Christie Trapp
