MG John Glover Castles was born 1 Jan 1925 in East Orange, New Jersey. He was the youngest of the 3 children born to Eugene Franklyn and Julia L. (South) Castles. His father was a native of New York City and a fabric designer and manufacturer. His mother's family had long been living in Franklin County, Kentucky and several ancestors had been keepers or assistant keepers at the state penitentiary, postmasters,and in other government posts. The couple had met when Eugene was working as a manager of a Frankfort, Kentucky store and delivered the then Miss South's wedding dress for her marriage to another New York City man. The couple hit it off and were married in 1909 and they initially lived in Louisville, Kentucky.
Soon after John was born the family was living at 428 Ridgewood Avenue in Glenn Ridge, New Jersey in a home valued at $75,000 in 1930 together with 2 servants one of whom was the butler. However, the Great Depression had an obvious impact on the family as there were no live-in servants in 1940 and the family had moved down the block to 443 Ridgewood Avenue to a home then valued at $25,000. His father reported a 1939 income of $5,000 and was still designing fabrics. Being from a well-to-do family, John (or "Jack" as he would be called later in life) was able to graduate from Valley Forge Military Academy in 1943. He attended University of Virginia in Charlottesville, Virginia.
In 1943 he enlisted in the Army and attended OCS class 362-44 at Fort Benning, GA. He was initially commissioned as a 2LT on 22 Nov 1944. 2LT Castles would go on to serve as a platoon leader in Europe with the 345th Infantry Regiment in the 87th Infantry Division during WWII during which time he was awarded the Bronze Star. Discharged in April 1945 he returned to school. He married Dorothy Towles Rowe on 15 Apr 1950 and completed his BS degree in Economics at the University of Virginia shortly after in that same year. John originally joined the Virginia National Guard’s Charlottesville-based K Company 116th Infantry in May 1949 while he was attending the University. Promoted to CPT on 2 Mar 1953 and MAJ on 11 Mar 1957. John began work for the Farmers Home Administration in Fredericksburg before that office closed and moving to the Culpeper office as supervisor in 1959.
John and Dorothy had their first child, a daughter in January 1961. A near tragedy occurred on 30 Aug 1961 when John's stalled car was struck by a train at a crossing near Barboursville, Virginia. His left leg had to be amputated below the knee and he suffered a fractured pelvis. However, this didn't stop his military career, John attended the United States Command and General Staff College again in 1964. In May of that same year John and Dorothy had a son. Confirmed as a BG in 1974, he commanded the 116th Infantry Brigade (Separate) from 1977 to 1980. BG Castles was appointed the Adjutant General of Virginia (TAG) in August 1982 and confirmed as a MG on 24 Feb 1983. During his tenure as TAG, the Virginia National Guard went from ranking 50th in the nation to 1st in 1994.
