Alexander Ross was born in 1840.
Alexander was 21 years old and living in Bath, Clinton County, Michigan, when he enlisted in Company G on May 10, 1861. He was wounded severely in the groin on May 31, 1862, at Fair Oaks, Virginia. By mid-June he was hospitalized in Portsmouth, Virginia, and apparently returned to duty soon afterwards. Homer Thayer of Company G reported on September 2 that that Ross had been wounded slightly at Second Bull Run on August 29, 1862.
Slight or not, he was subsequently hospitalized in Washington, DC, and died from a wound to the ankle on September 26, 1862, at Presbyterian hospital in Georgetown, DC. He was buried in the Military Asylum cemetery (Soldier's Home National cemetery), section F no. 848.
No pension seems to be available.
