Junius F. Crain was born around 1839, possibly in Ohio. By the early 1860s, he was living in Brookville, Pennsylvania. He enlisted in the Union army on September 1, 1862, and mustered in as a sergeant in Company I of the 148^th Pennsylvania Infantry later that day. He was 5 feet, 6 inches tall, with dark hair and blue eyes. He was promoted to 2^nd lieutenant on January 13, 1864, and he mustered out in Alexandria, Virginia, on June 1, 1865. He got married sometime after the war, and they had a son named Frank. His wife, however, died by the early 1900s, and he may have gotten re-married to a woman named Clara. He moved to Binghamton, New York, by the late 1880s, and he worked as a harness maker there. He applied for a federal pension on April 17, 1897, complaining of rheumatism. He was admitted to the National Home for Disabled Soldiers in Bath, New York, in 1904, and he remained there for the next three years. By 1910, he was boarding with several other harness makers in Bath. He died there on March 30, 1912, and was buried in Bath National Cemetery.
