Hello Lynn,
Did you ever find out an answer on the "Brick House"?
My soldier's (21st MS Infantry Co C) POW records show captured near Louden,TN. From the Knoxville prison they sent him to "the hospital" on Dec 21, 1863. He died Jan 8, 1864. Notes say he was buried at the "City Cemetery" in Knoxville. There is no city cemetery! Mclung and Mabry Hazen house have no records.
Did you have any luck with finding the Brick House?
Valarie
