The 7th MS battalion served with French’s Division, Sears’ Brigade alongside the 4th, 35th, 39th and 46th Mississippi regiments.
McGavock has a soldier named William Lott (#267) as buried in section #39 MS. He served in the 7th MS battallion with Company B.
Civil War Data (CWD) also lists a William Lott, Jr in Company G, 7th MS batt.
The question is:
. . . . is the William Lott (#267) buried in section #39, 7th MS battllion related to William Lott, Jr., in the CWD file?
If so, Lott #267 could likely be the father who died, serving with his son.
There is also a William Lott (#267) in section 41 of MS buried at McGavock listed as a member of there 15th MS. This is possibly the CWD William Lot with a Company E, 15th MS.
