Aitchison


Aitchison is a Scottish surname of Scots origin. It derives from the pet name Atkin, which is a diminutive of Adam.
Another variant of the name is Acheson. It corresponds to the English name Atkinson, which is particularly common in Northern England. At the time of the British Census of 1881, the relative frequency of the name Aitcheson was highest in Berwickshire, followed by Haddingtonshire, Roxburghshire, Selkirkshire, Peeblesshire, Dumfriesshire, Edinburghshire, Linlithgowshire, Northumberland and Lanarkshire. The Aitchisons are traditionally a mainly Borders and Lowlands family. They are considered to be a sept of Clan Gordon.
In Ireland, the name is common only in Ulster and particularly in counties Antrim and Down. Some Aitchisons are descended from Planters, although the name was recorded in Ireland before that period.
Acheson is a variation of the name in Scotland and the Border region, having been originally spelled Atzinson.
