Ferchar mac in t-sagairt

Fearchar of Ross or Ferchar mac in tSagairt (Fearchar mac an t-sagairt, often anglicized as Farquhar MacTaggart), was the first of the Scottish Ó Beólláin (O’Beolan, Beolan) family who received by Royal Grant the lands and Title of Mormaer or Earl of Ross (1223–1251) we know of from the thirteenth century, whose career brought Ross into the fold of the Scottish kings for the first time, and who is remembered as the founder of the Earldom of Ross.

The traditional story is that goes back to the work of the great William F. Skene, and indeed, even before him, with William Reeves, whom Skene cited. The historian Alexander Grant has recently challenged this theory, arguing that the evidence for this origin is far too thin to contradict the intuitive and well attested idea that he came from Easter Ross. Grant takes up the idea instead that mac an t-Sacairt (= Son of the Priest') probably refers to a background as keeper of the shrine to St Duthac, at Tain, Scotland.

However, despite "Ross" being a word describing the land the Earls managed (hence the Earl of Ross), Sir Robert Gordon (Earldom of Sutherland, P.36) states the Earls of Ross were first of the surname Ó Beólláin, and then were Leslies…) and continues on page 46 they are called by the surname Ó Beólláin through 1333 when "Hugh Beolan, Earl of Ross" is recorded as one of the slain at the battle of Halidon Hill. The surname remains as the surname of the Earls of Ross from Uilleam Ó Beólláin I, Earl of Ross until the death of Uilleam Ó Beólláin III, Earl of Ross in 1372 when his daughter, Euphemia I, Countess of Ross married to Sir Walter Leslie. Ross became the surname of the Earls of Ross much later in the history of the Earldom (much like the name "Windsor" is also used as the 20th century surname for the Royal Family).

Scholarly work on Fearchar has led to the conclusion that Fearchar was a native nobleman who benefitted by upholding the interests of the King of Scots. Fearchar emerges from nothingness in 1215, as the local warlord who crushed a large-scale revolt against the Scottish king, Alexander II. The Chronicle of Melrose reported that :
