A George W. Lowery was in Company F, 11th Texas Infantry Regiment. This was the only George in Texas and there are 12 in the Confederacy. This plus James should help. 37 Lowerys served for Texas in the Confederacy. You can see them all at
http://www.itd.nps.gov/cwss/soldiers.cfm which is the National Park Service. Put in Lowery, no first name, Confederacy and Texas. Should isolate all Lowerys.
