The name Yancy is of American origin and means "Created Name." The origin is the culture in which the name originated, or in the case of a word--the language in which it most appears.
Created by F. Scott Fitzgerald for his short story "The Popular Girl" published in 1922. Possibly a play on the word "Yankee," which was a colloquial term for "Northerner" in the U.S. during the Civil War. Yancy Butler, actress.
