Often, I am sidetracked and this would be a good example. Somewhere in the past I had heard of Mississippians who had been with General Morgan on his great Ohio raid. As far as I know there were no Mississippi Cavalry units with General Morgan in Ohio.
On Federal POW Records located at ancestry (22649 of 54896) some of Morgan's soldiers had a physical description including place of residence. Their unit seems to be Adams. I only know of Wirt Adams and the 28th Mississippi Cavalry and I don't believe he was with Morgan on his Indiana and Ohio Raid but rather around Vicksburg, Mississippi at the time the raid took place in July of 1863.
It is plausible that some of the soldiers with Morgan may have been from Mississippi however I can't find an Adams unit with Kentucky either.
The majority of soldiers listed their residence as Vicksburg, Mississippi. I have wondered if some of Wirt Adams soldiers had been taken as POW and simply put in with Morgan but this does not seem to hold water either with checking the names of Fold 3.
David Upton may be of help with one soldier. His name was George Hubbard and it looks like his residence is Simpson County, Mississippi although it might have been Simpson County, Missouri but Simpson County, Missouri did not exist as far as I know. George Hubbard's physical description was Age 20 (Born about 1843) 5' 7" in height with Light hair and Light complexion with grey eyes.
A common denominator with some soldiers listed seems to be an obscure unit from Mississippi that I'm not aware of and is not on Fold 3. Sorry to say I have forgot the name but I did see Wirt Adams name within the title.
Too have all of these physical descriptions and not finding a unit associated with them is frustrating.
