Witwicky is a real name... but a vanishingly rare one. The U.S. Social Security Death Index records the passing of only two people with that name in the United States in the last 50 years. However, the alternate spelling Witwicki is a relatively more common one, occurring 33 times in the Social Security Death Index. It is possible that the name originates from the Poland/Ukraine area of Eastern Europe, specifically the village of Witwica, and that the name itself means 'the one from Witwica'.
