McFarland, is a variation of MacFarlane that became popular in northern Ireland, but can be found worldwide.
This area was granted by feudal charter to one of the younger sons of the second earl of Lennox in 1286.
The history of this exchange is found in an old Celtic genealogy of Duncan, the eighth Earl of Lennox, who was executed in 1425.
This Alwyn had many sons, the eldest being Maldouen, the third Earl, who granted his younger brother, Gilchrist, the lands of Arrochar.
In 1344, Parlan's son, Malcolm MacPharlain, renewed the charter for the lands of Arrochar from Donald, the 6th Earl of Lennox.
