The 3 wisemen

....and their supposed names Casper, Balthasar and Melchior are nowhere mentioned in the Bible.Also note that the Magi did not visit the stable, as often depicted; they went to Joseph and Mary's house in Bethlehem. It was the shepherds that came to the stable.

The Western tradition of the names of the Magi derive from an early 6th Century Greek manuscript, translated into the Latin Excerpta Latina Barbari. The description seems to be of a mosaic of the magi, possibly those at Ravenna. A pseudo-Bedan text, Collectanea or Excerpta et Collectanea apparently continues the tradition of three kings. The text is said to be from the 8th or 9th century, of Irish origin, and first found in a printed edition of works ascribed to St. Bede the Venerable (673-735) at Basel in 1563.source: http://www.hymnsandcarolsofchristmas.com/...and_their_na.htm
