Thomas Babington Macaulay, 1st Baron Macaulay was granted (English) arms that alluded to those of the MacAulays of Ardincaple. This was despite his having no connection at all with Clan MacAulay; he was descended from the unrelated Macaulays of Lewis. According to Stodart, the fess checquy and buckles, prominent in 'MacAulay heraldry', are derived from the arms of the Stewarts. The basic Stewart coat of arms is blazoned: Or, a fess chequy azure and argent. The buckles used in 'Stewart heraldry' are ultimately derived from the canting arms of Alexander Boncle (d. by 1300), blazoned: gules, three buckles Or. Boncle's daughter (who in time became his heiress) married Sir John Stewart (d. 1298), younger son of Alexander Stewart, 4th High Steward of Scotland. Together the couple founded the 'Bonkyl' Stewart branch of the clan, and their descendants tended to use the 'Bonkyl' buckles as their heraldic differencing. One of the couple's sons, Sir Allan Stewart of Dreghorn (d. 1333), founded the Stewart of Darnley branch of the clan, which in time became the earls and dukes of Lennox. Tartan There have been several published tartans associated with the surname MacAulay.

William Buchanan of Auchmar's 18th-century account of the surname MacAulay states that the original member of this sept was a MacAulay. This sept dwelt in the lands of Sonachan, on Loch Awe, in what is largely Clan Campbell territory. The earliest account of the sept is in 1439, when Domenicus M'Federan was granted confirmation for the lands of Sonachan by Sir Duncan Campbell of Lochawe. According to David Sellar, the MacArthurs of Darleith descend from the MacAulays of Ardincaple. Darleith is located quite close to the old MacAulay seat at Ardincaple, about . In popular culture A fictional "M'Aulay" clan appeared in Walter Scott's 1819 novel, A Legend of Montrose, which was set during the James Graham, 5th Earl of Montrose's Highland campaign against the Covenanters in 1644. One of the main characters within the novel is Allan M'Aulay, a member of Montrose's army, and the younger brother to Angus, the clan's chief. Within the novel, Allan M'Aulay feuds with the MacEaghs, who are also known as the "children
