Re: SE MISSOURI
I have a confederate ancestor with confusing info on his service cards. One states that he deserted and joined the Union/enemy side. We finally found that he had been arrested when he had returned home at one point, the family had put up bond and he taken the oath not to raise arms again against the Federals. He did serve more in the Confederacy and was captured and then was pressed into service for a time as a teamster driving supply wagons betw the railhead at Rolla to Springfield. This was considered serving the Union Army. I have been told this even qualified him for a Union pension. Am still collecting info and trying to piece the story together, but perhaps something similar happened with your ancestor and so placed them on Union rolls.
