Show ContentsAillason History, Family Crest & Coats of Arms

In the mountains of Scotland's west coast and on the Hebrides islands, the ancestors of the Aillason family were born. Their name comes from the name for the son of "Ellis" or Ellis' son. Conversely, the surname could be is derived from "Alice" as in "the son of Alice." It is likely though that the name was derived from "Ellis" rather than the female personal name. 1 2

But Black goes on stating there is some dispute as to the origin: "On the other hand, with reference to Scottish Alison or Allison, Mr. L. A. Morrison in his The History of the Alison or Allison family in Europe and America, Boston, 1893, says that it is 'a fact beyond doubt that Alison comes from Alister or Alexander, and, further, that the Alisons are offshoots of the famous Clan of MacAlister" (p. 4), and that the origin of the name is due to two sons of Alexander MacAlister of Loupe who with some of their followers escaped to the parish of Avondale, Lanarkshire, during the War of Independence, and there later their name was changed from MacAlister to Alison (p. 18). He further states that 'the names Alison, Allison, Alinson, Allinson, and of Elison, Ellison, Elissen, Ellysen, are found thus spelled in the early history of some branches of the present Allison family. They are interchangeably mixed. The name was often spelled Ellison and Allison when referring to the same individual.' " 1

Early Origins of the Aillason family

The surname Aillason was first found in the county of Lanarkshire (Gaelic: Siorrachd Lannraig) a former county in the central Strathclyde region of Scotland, now divided into the Council Areas of North Lanarkshire, South Lanarkshire, and the City of Glasgow, where they acquired some time before 1300 the territories of their family seat at Loupe. They were descended from Angus Mor MacDonnell, Lord of the Isles, their Gaelic name was MacAllister, and it is difficult through history to distinguish one name from the other.

One of the first clear records of the family was "Patrick Alissone del counte de Berewyk rendered homage, 1296." 1 This is an early record of Patrick's swearing allegiance to King Edward I of England, shortly after his invasion of Scotland.

Continuing, we found "Peter Alesoun was a witness in Brechin, 1490 (REB,, II, 134), Thomas Alesoun appears in Lochtoun, Scone, 1586 (Scon, p. 232), James Allasone was bailie of Ranfrew, 1688 (RPC., 3. ser. XIII, p. 243), and Gabriel Alason was bailie of the burgh of Dumfries, 1693." 1

Migration of the Aillason family

Scottish settlers arrived in many of the communities that became the backbones of the United States and Canada. Many stayed, but some headed west for the endless open country of the prairies. In the American War of Independence, many Scots who remained loyal to England re-settled in Canada as United Empire Loyalists. Scots across North America were able to recover much of their lost heritage in the 20th century as Clan societies and highland games sprang up across North America. Early immigration and passenger lists have documented some of the first Aillasons to arrive on North American shores: William Allison who settled in Pennsylvania in 1764.
