Clan MacAulay

MacAulay covers two separate families, the MacAulays of Ardincaple on the Gareloch and the MacAulays of Uig on Lewis. The clan has no chief recognised by the Lord Lyon.

History

The name is Gaelic MacAmhlaidh, 'son of Aulay', and Aulay is a form of the Norse Olaf. That much is agreed. What is not agreed is whether everyone called MacAulay shares one origin. The Clan MacAulay Association says its DNA project has found several genetically separate MacAulay families, including more than one on Lewis and another in Wester Ross. We treat Ardincaple and Lewis here and keep them apart.

The MacAulays of Ardincaple held land at the mouth of the Gareloch, around Rhu and Helensburgh. One account says the Earl of Lennox granted Aulay of Faslane the lands about 1225, but that is a late-recorded tradition. The earliest figure on record is Maurice de Ardincaple, whose name appears among those pledging loyalty to Edward I in 1296. A bond of 1406 between his son Arthur and the Earl of Lennox names Colquhoun of Luss as the chief Arthur looked to. The family seems to have taken the MacAulay surname only in the sixteenth century.

Where the family came from is disputed. One tradition makes them a cadet line of the Earls of Lennox, a view favoured in some older accounts. Another rests on a bond of 1591 with MacGregor of Glenstrae, in which both sides claim descent from the same old stock, the 'M'Alpins'. Some writers suspect Ardincaple signed mainly to protect himself from MacGregor revenge, so the bond may say more about politics than blood. The Register still records a tartan linking MacAulay to the MacGregors.

Aulay MacAulay, the last chief of the Ardincaple line, sold the castle and estates to the Duke of Argyll in 1767. The line ended with him.

The Lewis MacAulays were a separate family, centred on Uig in the south-west of the island. Hebridean Connections places them in Uig well before the sixteenth century, but the written record stops at Dugald, whose son Dòmhnall Cam (Donald Cam) lived roughly 1560 to 1640. Uig still tells stories of Dòmhnall Cam, and some local families trace their descent to him. Much of that oral tradition concerns feuding with the Morrisons of Ness, so it is best read as tradition rather than record.

Today there is no chief recognised by the Lord Lyon. A clan commander was appointed in 1997, and the Clan MacAulay Association was re-formed in 1998. The Lord Lyon, Robin Blair, declined a petition for chiefship in 2002, ruling that ten years must pass after a commander's appointment before a chief could be considered. The Association has since elected its own chief for fixed terms, adapting the old tanistry custom. That is a clan arrangement, not a Lyon-recognised title, and we do not name the present holder.

Clan MacAulay tartans

Names and reference numbers follow the Scottish Register of Tartans. Mills sell most setts in modern, ancient and weathered colourways. The pattern is the same; only the shades change.

Get the kilt

When you order a kilt, ask for the tartan by its full name — for example “MacAulay” — and say which colourway you want. “Modern” is dark and strong, “ancient” is lighter, “weathered” is muted. The sett is the same in each.

We are choosing retailers we trust and will list them here soon.

Wear the colours

Our own MacAulay range is on its way: the name, the tartan and the motto on a heavyweight tee, a hoodie and a mug. About the shop.

“Associated” means the name appears in published sept lists for this clan. It does not prove descent, and many names are linked to more than one clan. Where your family lived is often the better clue.

Questions people ask

What is the MacAulay tartan?

The main MacAulay sett in the Scottish Register of Tartans is black, red, green and a pale grey, and dates to 1880 or earlier. There is also a Hunting sett and a separate MacAulay of Lewis tartan designed in 1992.

Does Clan MacAulay have a chief?

Not one recognised by the Lord Lyon. The Lord Lyon declined a petition in 2002, and the Clan MacAulay Association now elects its own chief by clan custom.

What is the MacAulay motto?

The motto is Dulce periculum, Latin for 'danger is sweet'. The crest on the clan badge is a boot with a spur.

Are the MacAulays of Lewis and Ardincaple the same clan?

The Clan MacAulay Association's DNA project found the groups genetically distinct, and the Register describes the Lewis MacAulays as a quite separate family. The surname is shared, but the origins are not.
