Sir John Stirling of Edzell. [Burke's Peerage]
-------------------------------------
The next proprietors of Glenesk of whom we have any knowledge are the Stirlings. It is not known whether they followed immediately after the other owners we have noticed, or if there was an intermediate proprietary race. The family whence they sprung is not certainly known, but it is probable they were of the same stock as the family of Keir, the armorial bearings of both having points in common. In what manner, or from whom, they acquired Glenesk is also unknown. Besides possessing Glenesk, Edzell, and Lethnot, they were also the proprietors of large estates in Inverness and Moray shires, and they were sometimes designed ‘de Moravia’. In Ragman Rolls they are so styled, and several others of them swore fealty to Edward I at same time, as did ‘de Glenesk’.
