Frank

From an Old German name that referred to a member of the Germanic tribe, the Franks. The Franks settled in the regions now called France, Belgium and the Netherlands in the 3rd and 4th century. They possibly derived their tribal name from a type of spear that they used, from Proto-Germanic *frankô. From medieval times, the various forms of this name have been commonly conflated with the various forms of Francis. In modern times it is sometimes used as a short form of Francis or Franklin.

The name was brought to England by the Normans. Notable bearers include author L. Frank Baum (1856-1919), architect Frank Lloyd Wright (1867-1959), and singer Frank Sinatra (1915-1998).
