Humbie is a hamlet and rural parish in East Lothian, Scotland. It lies in the south-west of the county, approximately 10 miles south-west of Haddington and 15 miles south-east of Edinburgh. Humbie as we know it today was formed as the result of the union between Keith Marischal and Keith Hundeby in 1618.
Originally, Humbie formed part of the Barony of Keith, and was anciently known as Keith Hundeby. The lands were held by Simon Fraser of Keith in the reign of David I. A charter signed by Fraser in 1191 is said to be the first mention of the Anglo-Norman Frasers and the Barony in extant records. Keith Marischal House stands a mile to the NNW of Humbie, and was the caput of the ancient barony. It is a long house with a vaulted ground floor, built in 1589 by the Keiths, who were then Grand Marischals of Scotland. The north front was baronialized in 1889 by Kinnear & Peddie. Interior decorations and fireplaces were done circa 1740, 1800, 1820, and 1869.
