Origin: Scottish

Meaning: Son of Alasdair

Macallister is a boy’s name from Scotland. As the anglicized form of Mac Alasdair, it means to say “son of Alasdair.” Alasdair, in turn, is the Gaelic version of Alexander. Interestingly, it’s agreed upon that all bearers of McAllister and the likes of it, share a common ancestor, whom the historians believe to be a mid-12th century lord known as Somerled. And although this name is usually used as a surname, like in the case of Kevin McCallister, the boy tyrant and childhood hero in Home Alone, you can for sure set baby apart by using it as their first name.
