Origin of the name Casper:

Dutch form of Gaspar, which, along with Balthasar and Melchior, was assigned to the Three Wise Men who brought gifts to the Christ Child. The names are not found in the Bible and are thought to have been assigned in the 11th century. Of uncertain etymology, Caspar might be derived from the Persian genashber (treasure master), which is in keeping with his role of the bringer of precious gifts.
