Origin of the name Jasper:

English form of Gaspar, a name of uncertain etymology 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 fixed in the 11th century. Gaspar might have been derived from the Persian genashber (treasure master), which is in keeping with his role of the bringer of precious gifts.
