See Jervise (1861 71-5) for an account of the McComies in Glenisla and Glenshee, where they held Finegand in 1571 (Black 1946, 474). The McComies seem to have been significant in the dissemination of the myths and legends of Finn mac Cumhail. It is known that the author of a ‘short poem allusions to several individuals famous in Gaelic mythology’ in the Book of the Dean of Lismore was one Baron Ewan McComie (Black 1946, 474).

Canmore has the following entry:

A large stone shaped like a chair without arms, and a well, where McComie refreshed himself while walking the old road to Glenshee up Glen Beanie. The wife of the tenant at Crandart, where there is a stone bearing McComie’s name and the date 1660, stated in 1863 that there were letters carved on the back of the chair.
Name Book 1863
Neither the stone or well could be located. The grieve at “Dalvanie” could offer no information regarding the stone or its location. Enquiries at Crandart also proved negative.
