I'm not sure if it would help in what you are trying to put together, but I have some information on one of the soliders in Vospers Sharpshooters.
An ancestor of mine, Ozial Davis, served in Vospers Sharpshooters and was KIA at Petersburg.
I have a copy of a letter that he wrote home while they were encamped at Annapolis as well as copies of various papers with munster information.
