I am trying to find info on a family member named Daniel Calhoun Neel.

His tombstone states

Co. G
8 Texas INF
CSA

I am also trying get info on his brother Ira G. Neal (his tombstone has the last name spelled differently, but they are brothers)

His tombstone states

Co. G
12 REGT
Texas INF
CSA

Thanks so much for any help you can give.
