my ggggrandfather, John Stevens(of Cincinnati,OH), was a fireman on the first train run on the P.R.R., carrying Union soldiers to the south and was killed in 1861 according to a letter that I have. I am thinking that he may have been part of the early battles of West Virginia(possibly Philippi) as they involved regiments from Ohio. I have seen that engineers and other railroad employees did not have to enlist for the Union, but instead ran the trains since they knew how to. He was listed as an engineer in the 1850 census, so I'm thinking that he may not have enlisted, but rather have just been a fireman as it was his trade. My question is, where would the engineers be buried if killed in action if they were not enlisted? thanks, Charlie
