his actual surname was "le bailly", though he and other members of his family used "le bailly de la falaise", referring to an ancestral estate; it is typically abbreviated to "de la falaise". as the marquis told "the new york times" (october 7, 1925), "my patronymic name is le bailly, but ... i use the name de la falaise because it is one of the great-grandfather branches of the le bailly family. de la falaise is the only existing branch of that family today. so this should be my entire name: james henry le bailly de la falaise, marquis de la coudraye".
