Henry Oberbeck was the foster-brother of John Peters. Both played together on the 1883 Alleghenys, and Peters was also around for the 1882 and 1884 seasons.
Ray Rohwer played for the 1921-22 Pirates. His brother Claude Rohwer spent 44 days on the active roster in 1922, but the only game he played was an in-season exhibition game, so he doesn’t appear in the record books.
