Jason:
I have a similar subset of New Jersey Old Judge players/managers/umpires, but mine includes those that died in New Jersey as well. I suspect you are going to find you have quite a few Massachusetts players to acquire including a few HOFers.
From my original list of 29 I am down to needing only two to complete my subset - Buster Hoover and Frank Hankinson (who died in my hometown of Palisades Park).
Can anyone help a brother out?
