Last name origins & meanings:

  1. Polish: from Polish wilk ‘wolf’, probably from an Old Slavic personal name containing this element, but perhaps also applied as a nickname for someone thought to resemble a wolf or connected with wolves.
  2. Scottish and English: from a medieval personal name, a back-formation from Wilkin, as if that contained the Anglo-Norman French diminutive suffix -in.
  3. North German: variant of Wilke.
