The ancestors of the McAllaster family come from the ancient Scottish kingdom of Dalriada. Their surname comes from the Gaelic Mac Alasdair "son of Alasdair," which correlates to the personal name Alexander.

Early Origins of the McAllaster family

The surname McAllaster 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.

McAllaster Spelling Variations

Medieval spelling was at best an intuitive process, and translation between Gaelic and English was no more effective. These factors caused an enormous number of spelling variations in Dalriadan names. In fact, it was not uncommon to see a father and son who spelled their name differently. Over the years, McAllaster has been spelled MacAlister, MacAllister, MacAllaster, MacAllestair, MacAllester, MacAllister and many more.

Settlers from Scotland put down roots in communities all along the east coast of North America. Some moved north from the American colonies to Canada as United Empire Loyalists during the American War of Independence. As Clan societies and highland games started in North America in the 20th century many Scots rediscovered parts of their heritage.

The McAllaster 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.
