The short story

Mack is a short surname with several documented origins. In Scottish and Irish contexts it can be a reduced form of longer surnames beginning with Mac or Mc, from Gaelic mac, “son.” In North German and Dutch usage it may come from the personal name Macco or Makko, a diminutive built on an element for “kinsman.” Older Norse and Irish forms such as Maccus also appear in British records. Mac, Mak, and Mackey are comparison spellings, not one lineage. Parent’s name is the closest catalog type for the personal-name and Mac-patronymic routes. Disputed confidence is required.
