He was the son of Sir William de Brechin by Elena Comyn, daughter of Alexander Comyn, Earl of Buchan and Elizabeth de Quincy. Sir William was the son of Henry of Brechin, an illegitimate son of David of Scotland, Earl of Huntingdon.[1] Brechin is first attested to as a ward of a Sir John de Callendar in 1292.[2]
Continuing in English service, Brechin was present at the Battle of Inverurie, and according to John Barbour, he retired after the battle to Brechin Castle where he was besieged by David Earl of Atholl.[8] However this is contested by the historian and genealogist Sir James Balfour Paul.[9] According to all records, Strathbogie was still in the service of the English, so the capture of Brechin Castle must have been accomplished by another of King Robert's following.[10]
At a parliament at Scone (later known as the Black Parliament) in August that year, Brechin was found complicit along with William de Soules, the Countess of Strathearn and others in a conspiracy to depose the king. For this offence Brechin was executed.[11]
Although there is no reason to doubt his guilt, his execution surprised many people, as he was seen as a "flower of chivalry", having acquitted himself well in battle against the Saracens during the crusades.
Marriages and issue
Brechin appears to have married Margaret de Bonkyll, widow of Sir John Stewart of Bonkyll, by 1304 when she is recorded as his wife.[12] and had issue.
