MacMillan History, Family Crest & Coats of Arms
The rugged western mountains of Scotland's coastline and the Hebrides islands were home to the ancestors of the MacMillan family. MacMillan was originally a name for a bald person; the name may refer to a member of a religious order. The Gaelic forms of the name are Mac Mhaolain or Mac Ghille Mhaoil, both of which mean son of the bald or tonsured one.
However, the origins of the Clan have been shrouded in uncertainty, largely as a result of historians of the Clan Buchanan, and their insistence that both Clans have a common ancestry. Buchanan of Auchmar says that the MacMillans are descended from Methlan, second son of Anselan, a Buchanan Chief of the thirteenth century. His theory supports the Buchanan claim that the MacMillans are but a sept (sub-Clan) of the Buchanan rather than a Clan in their own right. This theory is supported by the contention that both Clans have an ecclesiastical origin: MacMillan being Anglicized from Maolanach, meaning a 'priest.' However, tradition may more properly ascribe the origin from a particular tribe in Moray that has descended from the ancient Pictish tribe of Kanteai, thought to have existed in the first half of the second century AD.
Early Origins of the MacMillan family
The surname MacMillan was first found in at Tayside, where in 1263 Cilleonan MacMolan appears on documents.  They arrived in Strathtay from the lands in Loch Arkaig after King Malcolm IV transplanted many Clans, including the MacMillans, from that region about 1160 AD. Later, about 1350, the Camerons, who had changed their name to Chalmers, drove them from their Strathtay territories.
In vacating the Strathtay, the Clan branched to many other areas, including Lochaber, Argyll and Galloway. The senior branch, however, were the MacMillans of Knapdale, and they held a grant from the Lord of the Isles inscribed in Latin on a rock at Knap: 'MacMillan's right to Knap shall be, as long as this rock withstands the sea.'
Malcolm Mor MacMillan had received this rock by the 14th century. His grandson Lachlan MacMillan died at the Battle of Harlaw in 1411. Lachlan's son, Alan MacMillan of Knap, married the McNeill heiress and took over the Castle Sween. He erected a cross, which still stands to this day in Kilmory churchyard. The cross stands better than twelve feet high and is elaborately engraved, showing a Highland Chief hunting a deer on one side, and a claymore surmounted by certain Clan members on the other.

Some of the MacMillan family moved to Ireland, but this topic is not covered in this excerpt.
The hardy Scots who made the crossing settled all along the east coast of North America and in the great west that was just then opening up. At the time of the American War of Independence, many United Empire Loyalists moved north from the American colonies to Canada. Scottish national heritage became better known in North America in the 20th century through highland games and other patriotic events. An examination of immigration records and passenger ship lists revealed that people bearing the name MacMillan arrived in North America very early:

Emigration to New Zealand followed in the footsteps of the European explorers, such as Captain Cook (1769-70): first came sealers, whalers, missionaries, and traders. By 1838, the British New Zealand Company had begun buying land from the Maori tribes, and selling it to settlers, and, after the Treaty of Waitangi in 1840, many British families set out on the arduous six month journey from Britain to Aotearoa to start a new life. Early immigrants include:

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Miseris succurrere disco
Motto Translation: I learn to succour the distressed.
