The Mayflower Society offers a Mayflower Lineage Match, where they will take your proposed Mayflower line (submitted on-line) for $75, and respond whether you have a valid line, and if there are others who have proven the same lineage, beyond the 5th generation. That report usually takes 2-4 weeks, but may be slowed due to the upcoming 400th Anniversary.
I am not aware of any American Ancestors program that does the same thing, unless they are simply supporting the Mayflower Society's lineage match program.
