Show ContentsMcLachlan History, Family Crest & Coats of Arms

The ancient Dalriadan clans of Scotland spawned the name McLachlan. It is derived from the personal name Lachlann. The Gaelic form of the name is Mac Lachlainn, denoting the son of Lachlann. Although most feel Lachlan Mor, a great Chief who lived by Loch Fyne in the thirteenth century, is the Clan founder, the legend of descent from the ancient Gaelic King, Niall of the Nine Hostages, who reigned in 400 AD, offers some clues as to the clan's early origins.

Lochlann, in old Gaelic means literally, 'Norway,' and was the favorite Christian name of the royal house of O'Neill in Northern Ireland, a house descended from Niall of the Nine hostages, and said to be the family with the oldest history in Europe. A branch of the O'Neill's took the surname MacLochlain and soon became rival Kings to the O'Neills.

King Brian O'Neill slew the last King Domnall MacLochlainn. His son Anrothan, who was ancestor of the MacLachlans in Scotland, married the daughter of the King of Scots, thereby gaining the inheritance of Cowall and Knapdale in Scotland. Anrothan MacLachlan was progenitor of the MacLachlans of Strathlachlan, the Lamonts, the Lyons, the MacSorleys, the MacEwans, and the MacMillans. It was in the mid-twelfth century that each of these branches separated into distinct entities.

Early Origins of the McLachlan family

The surname McLachlan was first found in Argyllshire (Gaelic erra Ghaidheal), the region of western Scotland corresponding roughly with the ancient Kingdom of Dál Riata, in the Strathclyde region of Scotland, now part of the Council Area of Argyll and Bute, where this Clan first settled in Scotland in 1100 when Lachlan was heir of Fergus, Lord of Galloway. In 1238, a charter recorded Lachlan Mor's father increasing the endowment to Paisley Abbey.

When, in 1292, King John Baliol erected Argyll into a sheriffdom, Gillescop MacLachlan was one of the twelve principal barons whose land it encompassed. In 1296, Ewen MacLachlan was forced to swear loyalty to the English King Edward I, but this loyalty was formally changed back to Scotland in 1305, when Gillescop MacLachlan, like his neighbors the Campbells, swore allegiance to Robert the Bruce. Gillescop was a member of the Barons of Bruce's first parliament at St. Andrews, in 1308. 1

King John of England (reigned: 1199-1216) was also known as John Lackland from the Norman French, "Johan sanz Terre" or "John without land."

McLachlan has appeared as MacLachlan, Lachlan, MacLachlane, McGlothan, McGlothin, MacLauchlan, MacLauchlane, MacLauchlin, MacLaughlin, Lauchlan and many more.

United States McLachlan migration to the United States +

Many settled along the east coast of what would become the United States and Canada. As the American War of Independence broke out, those who remained loyal to the crown went north to Canada as United Empire Loyalists. The ancestors of all of these hardy Dalriadan-Scottish settlers began to recover their collective history in the 20th century with the advent of the vibrant culture fostered by highland games and Clan societies in North America. Highland games, clan societies, and other organizations generated much renewed interest in Scottish heritage in the 20th century. The McLachlan were among the earliest of the Scottish settlers as immigration passenger lists have shown:

The McLachlan Motto +

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: Fortis et fidus
Motto Translation: Brave and trusty.
