Duncan Green Campbell (1835-1888) was the only son of John Archibald Campbell (1811-1899), who was Associate Justice of the US Supreme Court (1853-1861) and Assistant Secretary of War in the Confederate government (1862-65), and Anne Esther Goldthwaite (1804-1883). He was probably named for his paternal grandfather Duncan Green(e) Campbell for whom Campbell County, Georgia was named. This Duncan married Ella S. Calvert (1840-1902) in 1861; they had four children together. She probably lived in Richmond with her father-in-law during the war. He served as a lieutenant in the Confederate Engineer Corps. He was promoted to captain in March 1864, and he served until April 1865. He settled in New Orleans after the war.
