He does fall outside of the current criteria for the PGM project (1620-1640), although some people have expressed a wish that the criteria should extend to 1650.
While I'm no longer co-leader of PGM, I would support PGM adopting this profile for purposes of protecting it, lacking any other project that might do so. (I think there was, at some time, talk of a broader colonial New England project that would include PGM and profiles through the US Revolution, but it never gained traction.)
THAT said, I think an argument can be made that for early profiles like this one, project or not, PPP tagging is appropriate when there is parental or origin conflict.
And, I doubt Anderson covered him; his Great Migration book series didn't even finish those through the 1630s, much less 1640 or later. However, I believe that NEHGS does have a project to extend Anderson's work and document all pre-1700 New England families.
