Mentioned in the Findagrave.com memorial for their grandson:
"[Edward Irving Darling was the] son of Flora (born Sophronia A.) Adams. She claimed his father to be one Edward I. Darling, a brigadier general in the Confederate army, who supposedly died of wounds at Franklin, Tennessee, on 29 November 1863. She described Edward as the son of C. Irving Darling and Marie Dumas Lafitte Darling of Louisiana, born 12 Dec 1819 in New Iberia, Louisiana, USA, and said that she had married him on 12 March 1860 in New York City. As yet, I have found no census records, military records, birth/death records, or any other evidence of the general's existence."
