Andrew G. Mallory stood 5-feet 2-inches tall, and weighed 147 pounds. He enlisted 22 March 1865 as a Private in Capt. Edward S. Gilligan's Company E, 88th Pennsylvania Infantry. He was honorably discharged while in hospital (for pneumonia) at Chester, Pennsylvania, on 30 June 1865.
In 1891 he applied for disability pension by reason of rheumatism, kidney disease, impaired vision and nearly total deafness of left ear. He was awarded $6 per month for his rheumatism. In 1896 he applied for an increase in pension, but died before it was processed. He left a 43-acre farm in Hayfield Township, Bloomfield County, Pennsylvania. Although married three times, Andrew had no children.
In December 1896, his widow, the former Eunice S. Bisbee, applied for a Widow's Pension. There is an interesting circumstance which was apparently overlooked by mutual consent: Andrew was never divorced from his second wife who died in 1878; he and Eunice married in 1876. Eunice collected a pension of $8 per month until her death in 1906.
