Clan Ross was designated by the Highlanders Clann Aindreas, and in the ancient genealogical history they are called Clann Anrias.
It begins with Paul MacTire, to whom William, Earl of Ross, Lord of Skye, granted a charter for the lands of Gairloch in 1366.
In Robertson's Index there is mention of a Ferquhard Ross, supposed to be the son of Gille Anrias, from whom the clan took its name. He founded the Abbey of Fearn, in Ross-shire, in the reign of Alexander II. This line ended with Euphemia, Countess of Ross, who resigned the Earldom to an uncle.
The Rosses of Balnagowan, a very ancient line, sprang from William, Earl of Ross, a friend of Robert I. His son, Hugh, was killed at Halidon Hill in 1333.
From Hugh Ross, second son of Hugh, Earl of Ross, the Balnagowan estates passed on from father to son to David, the last Laird of Balnagowan, who died without issue, when the estate and chiefship passed under entail along with the arms to Brigadier Charles Ross, son of George, 10th Lord Ross of Hawkhead. This line expired and the chief arms were confirmed by Lyon Court to Miss Ross of Pitcalnie.
The Rosses of Shandwick, Rosses of Invercharron, and Rosses of Pitcalnie are all branches from the Balnagowan family. The present Chief is David C. Ross of that Ilk.
