Thank you for this info. It eliminates that John M. Powers in the 1860 census as being my ancestor.
The search continues.

Do you know the age and residence of the John Powers you found in Co D, 2nd regiment
AL infantry who deserted Mar. 6, 1862 at Mobile?

He is not listed on the Alabama Civil War Service Database. Another John Powers,
age 23, Co F, 2nd regiment AL infantry is listed with the 24 other records.
