I have an ancestor named James H. Woods who had a son and daughter born in IL during Civil War. I find 3 soldiers with this name including middle initial in the 43rd, 80th, and 84th Regiments of Illinois Infantry. I only know my ancestor was living in Missouri by 1870, but married a RoeMary Self in TN before the war. Does anyone out there have any idea on how to tell which one is my ancestor?
