Charles Nungesser is probably the most "colorful" member of the family. I first heard of him during an episode of the American TV series, Young Indiana Jones. Charles, a WWI flying ace in the Lafayette Escadrille, was the central character. Read some of these biographies of a truly interesting character.
As if the stories of Charles doing combat with the Red Baron aren't enough, it seems that he may have flown the Atlantic before Lindbergh. Exactly what happened is still a bit of a mystery. Read about it at one of these links:
Where does Charles Nungesser fit into the family tree? That's an unanswered question. But it's probably a safe guess that he's descended from on of the family members that did not emigrate to America.
