From the experts:
Hyman is still down at the schvitz with Morty and Myron. Hyman was commonly used by first-generation Jewish immigrants to Anglicize Chaim, but similarities to terms like heinie and hymen have taken it out of the realm of modern possibility. The original Chaim would be preferable to Hyman.
