This name, which in Scotland is found principally in Galloway and Wigtownshire, is of Celtic origin, but a number of alternative derivations has been proposed. The Irish Gaelic ‘MacCu’uladh’, meaning ‘son of the Hound of Ulster’, is anglicised as ‘Maccullagh’. In Scots Gaelic it is often rendered ‘Maccullaich’, and translated as ‘son of the boar’. They are, of course, very similar, and both are references to descriptive personal names suggesting fierce vigour. There is also a more northerly branch of the family around Oban, descendants of the Macdougalls, who may derive their name from ‘MacLulaich’, which may mean ‘son of the little calf’. This, again, is a descriptive personal name and its significance is obscure. The progenitor of the Argyllshire Mccullochs was said to be Lulach, son of Gilla Comgan, the Celtic Mormaer, or Earl, of Moray. The Galloway Mccullochs first come to prominence when Thomas Maculagh, ‘Counte de Wyggtone’, appears on the Ragman Roll of 1296, rendering homage to Edward I of England. He may also be the same Thomas Makhulagh who was appointed sheriff of Wigtown in 1305. Mccullochs witnessed various charters throughout the fourteenth century and Sir Patrick M’Owlache is noted as being restored to his lands in 1363, having previously been forfeited, apparently for allegiance to the English. The family also lost the office of sheriff of Wigtown, which passed to the family of Agnew of Lochnaw who still hold this honorary title to this day. day. In 1488 Quinton Agnew, sheriff of Wigtown, was ordered to restore to Archibald McCulloch twenty-eight oxen, eighty-eight sheep, four horses and other goods. It is recorded in 1507 that the Mcculloch chief, in revenge for a raid on the town of Kirkcudbright, ravaged the Isle of Man, then in possession of the Earl of Derby. The Mccullochs appear to have acquired the lands of Myretoun, which were constituted into a barony around 1566. They were raised to the rank of baronet in 1634, but this title came to an unfortunate end when Sir Godfrey Mcculloch was executed at Edinburgh in 1697 for the murder of William Gordon. The trial was of such celebrity that it is recorded in Pitcairn’s Criminal Trials of Scotland. The representation of the family passed to cousins, the Mccullochs of Ardwall, and there were other cadets. Major General Sir Andrew Mcculloch of Ardwall served in both the Boer War (1899–1902) and the First World War (1914–18), winning the Dist-inguished Service Order no less than three times. He was aide-de-camp to George V from 1931 to 1933.
