Note that these are all mature men with families, which explains why they did not join earlier. Like most men in regiments organied at this time, they were obliged by the law of Apr 16, 1862, to serve in the Confederate military for three years or the war.
In 1860 James and Mary Stewart report as residents of White Water, Pike County AL. Benjamin F Stewart, age 13, is listed as oldest child remaining in this household. On the 1850 census of Bibb County GA, his age is listed as 4, so his his year of birth could be 1846. If he enlisted in the winter of 1863/64 while the Army of Tennessee camped at Dalton, Benjamin should have just turned 18 and military service would be required.
Benjamin's service file shows that he received clothing as a member of this company in the 2nd quarter of 1864. Like Richard, he was captured at Jonesboro GA, Aug 31, 1864, exchanged, and captured again at Nashville TN, Dec 16, 1864. He died of pneumonia at Camp Chase OH, Feb 15, 1865.
John J Stewart, age 23, reports on the census in the next household to James Stewart, post office Bibb. He is one of the original members of Capt McGuire's company, enlisting at Brundidge AL on May 2, 1862. He served as a butcher at Vicksburg and was paroled on July 9, 1863, after the garrison surrendered. John J Stewart was wounded near Marietta GA and sent to a hospital at Macon GA. Furloughed on July 11, 1864, he received clothing from the military post at Columbus GA the following day. He may not have been able to return to duty afterwards.
Joseph Hamp Stewart, age 32 when enlisted, He was paroled at Vicksburg on July 9, 1863, five days after the garrison surrendered. He received his final parole at Meridian MS, May 12, 1865, serving in the Commissary Dept under Maj A E Love. He was also in the hospital at Macon GA, admitted July 20, 1864 with chronic rheumatism.
We have already outlined Richard's military service and I'm not sure you have an interest in the others.
L Stewart is Lee Stewart, who enlisted at the mid-point of the war. He received a parole at Montgomery AL, June 5, 1865.
