In "The Wright-Chamberlin Genealogy," by Eunice Miena Barber, Richard Chamberlin (actually, Chamberline - the extra "e" was dropped in the next generation, as explained in the referenced book) is documented as having had a son who was born and died in 1642, which would make him too old to have been born in 1630. [Note that "The Wright-Chamberlin Genealogy" is freely available on Google Books.]
P.S. I am a carrier of Richard's y-DNA, although I have not had the y-DNA test performed.
