Actualy Santa doesn’t have a middle name. Santa Clause is a Germanified version of the name Saint Nicholas. At the time most people didn’t have last names and noone had middle names. He was an archbishop of Asia Minor a thousand or so years ago (I can’t remember centery off the top of my head). He was known for throwing small bags of gold down the chimneys of families who were too poor to afford dowreys for their daughters. It is also said by some that he brought three children back to life that had been murdered. Everything else has been added over the years.
