Virgil,
In regard to your side note. I also had a few ancestors in the 39th. If I remember correctly, this flag was captured at Allatoona Pass by the 4th Minnesota. I think it would be safe to assume that the unit would most likely received an Augusta Depot flag for the Franklin/Nashville campaign. If you happen to stumble upon any mention of the colors in your research, I would love to see it as well!
