I am researching Iowa residents who went South to serve the Confederacy. I'm trying to make sense of a limited service record for one former Iowa resident, Ambrose W. Key. He served in the 20th TX Infantry.

Key lived in Louisa County, Iowa, before moving to Texas in 1860. He settled in Washington County and then Fall County. He worked as a tanner in Fall County, Texas.

Key's record lists him as a Private, Co. C, 20 Texas Infantry for March 1865 at Galveston, with the remark, "Gain joined from Depot." The section "Absent Enlisted Men Accounted For" states, "On DS [detached service] Tanner, Falls Co,. Feb. 25, '65."

Ambrose Key signed his Parole of Honor on July 6, 1865, at Millican, Texas. The card notes that Key is in Capt Busters Co, Elmore's [20th] Texas Inft.

My questions:
1. Is it likely that Key worked as a tanner in Falls County, TX, for the 20th TX Infantry, in 1865?
2. Is it likely that Key joined a Texas unit earlier than 1865?
3. Is it likely that he was conscripted to do that work (in what turned out to be the last few months of the war)?

Thank you for thinking about my question.
