Mr. Walker-James and William would have been 16 and 18 years old respectively in 1861. The last information I had on them was an 1850 Census for Bartow County which listed both boys living with parents James and Mary, along with older brother Lafayette who was my great-great grandfather. I do not know why they would have been in Carrol County unless living with relatives there.
It is very possible that the James Bice listed as a member of 19th Georgia Inf Company K is in fact the boys father, James. The Senior James Bice would have been 54 years old in 1863.
Thanks so much for your input. Should you have any additional info on James and William I would greatly appreciate you forwarding it to me.

Respectfully

Steve White
