The 8th MS was part of Cleburne’s Division, Lowrey’s Brigade, 1st Brigade, Army of Tennessee.
The 8th MS fought with the 16th, 33rd, 45th Alabama; and the 5th, 32nd MS; and the 3rd MS battalion.
It is possible that the two Myers listed buried at McGavock were related. The muster roll for the 8th MS also lists two more soldiers by the same last name.
Jacobson (p. 84) lists the following boys in Mississippi Section 31 at McGavock.
#143 James M. Myers | 8th MS | Co. B | Lowrey | Confirmed in CWD
#144 George W. Myers | 8th MS | Co. B | Lowrey | Confirmed in CWD
CWD also lists:
John H. Myers, Co. B
T.J. Myers, Co. B.
Question: are they brothers or related?
