"Pretty Caroline" is an English song in G major and 2/4 time.
It was originally printed as a broadside ballad, probably between 1852 and 1859. It was collected from a Mrs. Powell in Herefordshire, July 1909. It is cataloged in the Roud Index of Folk Songs as #1448.
The song's theme is shared by a number of traditional folk ballads, generically known as "The Broken Token" family. Other songs from this family in this collection are:
      "John Riley"
      "Claudy Banks"
      "Dark Eyed Sailor".
Ralph Vaughan Williams used it as the second melody of the first movement of his English Folk Song Suite (1923) along with "Seventeen Come Sunday" and "Dives and Lazarus".
