Alistair
The story
Alistair is the English spelling of Alasdair, the Scottish Gaelic form of Alexander, so beneath the tartan it carries the same Greek meaning: defender of men. Scotland has used it for centuries in three spellings, Alistair, Alastair and Alasdair, all answering to Ally, as the footballer and broadcaster Ally McCoist, born Alistair, can attest. For American ears the name long carried a transatlantic polish, the voice of Alistair Cooke reading his Letter from America on the BBC for fifty-eight years. In US records it barely existed before the 1970s and climbed slowly for decades; the real acceleration is recent, and the name is at its most current in the 2020s. It reads as the fresh entry in the big Alexander constellation: more formal than Alex, less expected than Alexander itself, with the Scottish burr built in.
