Dear Robert,
It's rather late this evening, so I'll be short, but perhaps others can weigh in on your question.
It appears your Antone Miller was a member of Capt. Watts Cameron's Company of Texans. This same Watts Cameron later appears as a member of the 9th (aka, 5th) Kentucky Infantry. Also, included in Company "H" of this unit is one "Anton" Miller.
How they became a part of the 9th Kentucky, I don't know. This unit fought at Shiloh, Perryville, Murfreesboro, Chickamauga, etc. and were a part of the famous "Orphan" Brigade.
I'll be interested to see what others have to say about this Texas connection with a Kentucky unit.
Hope this helps,
Jim Martin
