The Farquharson crest includes a red lion holding a sword, on top of a cap of maintenance. The lion was taken by Alexader Nisbet in his 1722 System of Heraldry to be a reference to supposed descent of the Farquharsons from the MacDuff earls of Fife (along with the Wemyss, McIntosh and Fife surnames) via Farquhar Shaw. As such this is a royal lion, referring to Kenneth III of Scotland.
Alexander Farquharson of Invercauld registered his arms sometime between 1672 and 1678, which had the crest of a lion holding a dagger and the motto ‘I force no friends, I fear no foe’. However, his successor, John of Invercauld changed the motto in 1697 to ‘Fide et Fortitudine’, meaning ‘by fidelity and fortitude’ (R.R. Stoddart, Scottish Arms being a Collection of Armorial Bearings 1370-1678, p.342).
Bu 1909 the lion's dagger had been upgraded to a sword, although the cap was yet to be added (Fairbairn's Book of Crests). It was present by 1970 (Frank Adam, Clans, Septs and Regiments of the Scottish Highlands), so may have been introduced by Captain Alwyne Compton Farquharson of Invercauld, who succeeded in 1941, after the previous chief, Myrtle Farquharson, was killed in an air raid during the Second World War.
