Commander Nedwynn Flanders was the son of Sir Nederick Flanders and Augusta Wynd. He married Charlotte O'Tara and had a daughter called Nedna Flanders. He was a commander in the armed forces and fought during WWII. Presumably, the Flying Hellfish unit reported to him, due to Sergeant Abraham Simpson II, the leader of the unit, warned Private Charles Montgomery Burns that he'll report him to Commander Flanders if the latter doesn't leave the paintings in the German castle behind.
