Gaston

Gaston is a French name with medieval roots, possibly connected to a Germanic word for a guest or stranger. That explanation is plausible rather than certain. The name was used by nobles in southern France and is associated with Saint Gaston, another French name for the bishop also known as Vaast. Its documented French history is more secure than a single literal translation.

Two cultural references may come to mind for modern readers. Gaston Leroux wrote The Phantom of the Opera, while Gaston is the boastful antagonist in Disney's Beauty and the Beast. The fictional character is only one chapter in a much older name's history. Gastone is an Italian relative, and Gastón is the accented Spanish form, each adapting the French name to a different language.
