Was there an assassin on Grant's train?

[L Verge]

Laure, re.: 'And #3, it did refer to a man of color no matter his age" - perhaps I haven't understood correctly, but Joseph Hazelton, the program boy, was certainly not black, was he? I assume you mean any messenger refered to as "boy" was black?

One question in this context - what were (are) the duties of a valet?

I apologize if I wasn't clear, Eva. To the best of my knowledge, the use of the term "boy" could denote either black or white (or other races). I think it was used more prevalently to denote a young, white person (and probably one of "lower class") or a black man of any age. I'm basing this on 19th- and early-20th century standards.
