The original only has the border marked in yellow. I have tinted the Banffshire regions in yellow to make it clearer. Note the two areas in Aberdeenshire which were vitally part of Banffshire at this date.

A Brief History of Banffshire

When and why Banffshire was created is unclear, it certainly existed by the 13th century when the first sheriff of Banffshire is recorded.

In the 12th century the system of shires was introduced into Scotland, from the Anglo-Saxon system which had been first used in Wessex in the 9th century and gradually spread northwards. The sheriff or shire reeve was the person would presided over the shire court.

With the arrival of the Normans, counties largely replaced shires as administrative units, although the shire lived on in regional names and sheriffs.

Banffshire included the towns of MacDuff, Banff,Aberour, Cullen, Keith and Dufftown.

The borders of Banffshire changed over the centuries, and in 1826 it included two isolated areas surrounded by Aberdeenshire.

In 1975 Banffshire ceased to exist as an administrative area, and was divided between Moray to the west and Aberdeenshire to the east.
