I am trying to find military information on my GGG Grand father Isaac Smith who joined the 13th. Ky. Cavalry along with many members of our family. He enlisted at Whitesburg. In reading the roster for the 13th., there are two Isaac Smiths and I can't determine which is which. My grand father was born in 1820 and was married to Sitha Stacy. Can you help me with this? Thank you so much, Karen
