Beaton is a Scottish surname which may have multiple origins.
One origin of the name is from the placename Béthune, in Pas-de-Calais, France and is associated with the lowland clan Bethune.
Another derivation of the surname is an Anglicisation of the Scottish Gaelic Mac Beath,[1] and corresponds to the Beaton medical kindred of the Scottish Highlands and Western Isles.
The surname Beaton can be represented in modern Scottish Gaelic as Peutan (masculine form), and Pheutan (feminine).
[2] Another suggested derivation is from the mediaeval personal name Beaton or Beton, a pet form of a short form of the names Bartholomew or Beatrice.
