Middleton is one of those surnames derived from a place, and it is also one which, at an early date, appears in many localities both in England and Scotland. The Middletons treated of in this project descend from a family who settled in the Mearns or Kincardineshire, and assumed the style of Middleton *de eodem,' or of that Ilk. They are said to have obtained their lands in the time of David I., according to a charter by William the Lion to a Malcolm, son of Kenneth, cited by Nisbet on the authority of Sir George Mackenzie.
The original parish in Kindcardineshire, which named the Middleton clan and earldom, has later been renamed Fettercairn.
Several later clan members emigrated to places like Norway, the USA and others, and it is the projects intent to map out these connections.
