They are almost done digitizing the Missouri Civil War Service records on Footnote.com. The partial card shown here is for George Trautvetter, an Illinois resident who enlisted in a Missouri unit.
He enrolled in Keokuk, [Iowa], as shown on the "Joined for duty and enrolled" section of the card. Just goes to show that you always have to check those locations and remember that men might have served in units outside those of their state, particularly if states were having difficulty meeting their quotas.
Next is to get George's pension file. There's got to be something interesting in that. Casefile Clues readers know that the Trautvetters always leave an interesting series of records.
