Vaughn, also commonly spelled Vaughan, has been used quietly over the years, reaching a peak of Number 349 in 1949. It is now in the process of rediscovery, being seen as a good Sean alternative or an updated way to honor an ancestral Paul (which also means small).
In the recent past, Vaughn Meader was a comedian famed for his JFK impressions, and Vaughn Monroe was a popular singer-bandleader.
More frequently seen as a last name than a first, Vaughn has drawn particular attention in recent years via leading man Vince Vaughn, and before that was notable in the entertainment world by The Man from U.N.C.L.E. Robert Vaughn, singer Sarah Vaughan, and guitarist Stevie Ray Vaughan. Michael Vaughn is a fictional character on Alias, played by Michael Vartan.
