On the Scottish west coast, the Alasdair family was born among the ancient Dalriadan clans. Their name comes from the Gaelic Mac Alasdair "son of Alasdair," which correlates to the personal name Alexander.

Early Origins of the Alasdair family

The surname Alasdair 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 Alasdair Mòr was listed on record in 1253, as witnessing a charter by his brother, Aonghas Mór a Íle, to the Paisley Abbey.

Migration of the Alasdair family

These settlers arrived in North America at a time when the east was burgeoning with prosperous colonies and the expanses of the west were just being opened up. The American War of Independence was also imminent. Some Scots stayed to fight for a new country, while others who remained loyal went north as United Empire Loyalists. The ancestors of all of them went on to rediscover their heritage in the 20th century through highland games and other patriotic Scottish events. The Alasdair were among these contributors, for they have been located in early North American records: Charles MacAlister settled in Philadelphia in 1808; Daniel, David, Denis, James, John, Robert, Thomas and William MacAlister all arrived in Philadelphia between 1830 and 1870..

The Alasdair 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: Per mare per terras
Motto Translation: By sea and by land.
