- Edgar Gregory (the regiment's first Colonel) was a very religious man, motivated by his Calvinism to abolitionism
- Gregory regularly spoke at churches [e.g. 'City items' (Philadelphia Press (13 June 1863, page 2)]
- according to a letter from J H R Storey in 1906, the regiment was split between religious men, headed by Edgar Gregory, and others, headed by Eli Sellers, which led to "considerable friction"; Sellers allegedly called the religious men "Gregory's pets", and claimed that he "got even with" them when he became Lieutenant Colonel
- Adrian Beaugereau was raised as a Catholic, but "his army experience and four years' exposure to the rigid Calvinistic faith" led him to become a Presbyterian

[no privates in the 91st are listed, but the book lists very few privates; I suspect the author made more of an effort to determine which commissioned and non-commissioned officers were Jewish than privates.]
