Dion
A surname that usually comes from the given name Dion, ultimately tied to the Greek name of Dionysus, but in some cases it may also reflect a French form of Denis/Dionis.
The #4,225 most common surname in the United States (2010 Census) — about 1 in every 36,777 Americans shares it.
Etymology
Dion is most often a surname built from the personal name Dion. In French usage, Dion can be a shortened or related form of Dionis/Denis, and some historical notes connect it back to the ancient Greek name Dionysios, the source of Dionysus. That makes the surname, in broad terms, a name derived from a given name rather than from a place or occupation.
History
The surname is found in French-speaking areas and was carried into North America by French settlers and later migrants. Historical surname dictionaries sometimes treat it as a short form related to Dionis or Denis, while older classical scholarship also links the underlying name to Dionysus. Because the same spelling can arise through more than one naming path, family lines with this surname may not share a single origin.
