Hervey de Keith (died c. 1185) was a Scoto-Norman adventurer and nobleman and first recorded Marischal of Scotland.
[2] Latterly Keith had legal wrangles with the Abbey of Kelso as to the level of payment that he should make to them.
These troubles were smoothed out under the auspices of Jocelin, Bishop of Glasgow and Osbert, Prior of Paisley, who decreed that he must pay an annual sum of twenty shillings.
[3] Keith was Marischal under Kings Malcolm the Maiden and William the Lyon, and was witness to many charters under them.
It has been suggested that Keith married Margaret, daughter to William I, Lord of Douglas though this is doubtful.
