The two men:
--Pvt James Anderson- Co B, 11th Bat, Inf.- Queen of the West- the family were known to run tug boats on Sabine Lake.
--Pvt James Anderson, Co K Crescent Regiment
I believe are one in the same as both are shown enlisted on the same day in the same location and the 11th and the Crescent were later consolidated. This man was 25 years old when he enlisted. That should eliminate him.
