Mackaulei is in Origin.

Mackaulei is a modern, phonetic respelling of Macaulay/Macauley, a Scottish and Irish surname adopted as a given name. It derives from Gaelic Mac Amhlaoibh/Amhlaidh (“son of Amhlaoibh/Amhlaidh”), personal names borrowed from Old Norse Óláfr/Áleifr. Through this route the sense is “son of Olaf/Aulay,” with the Norse root leifr “heir, descendant” giving the underlying idea of “heir” or “ancestor’s descendant.” In some Irish lines it reflects Mac Amhalghaidh, of uncertain meaning.

As a surname it marked several Highland and Hebridean families (notably Lewis and Wester Ross) and Ulster Scots; as a given name it appears in the 19th century and rose in late 20th‑century anglophone use, helped by actor Macaulay Culkin. Variant forms include Macaulay, Macauley, McAuley, McCauley, MacAuley and MacAulay; short forms Mac, Cauley, or Coley. Mackaulei itself is rare and reads unisex in modern naming.
