Show ContentsAddair History, Family Crest & Coats of Arms

The earliest forms of hereditary surnames in Scotland were the patronymic surnames, which are derived from the father's given name, and metronymic surnames, which are derived from the mother's given name. Scottish patronymic names emerged as early as the mid-9th century. The patronyms were derived from a variety of given names that were of many different origins. The surname Addair is derived from the given name Edgar, which means prosperity.

Early Origins of the Addair family

The surname Addair was first found in Galloway (Gaelic: Gall-ghaidhealaibh), an area of southwestern Scotland, now part of the Council Area of Dumfries and Galloway, that formerly consisted of the counties of Wigtown (West Galloway) and Kirkcudbright (East Galloway). Tradition has it that the foundation of the family of Adair of Dunskey and Kinhilt originated from a fugitive son of Fitzgerald, Earl Desmond of Adair in Ireland. Desmond was descended from Otto Geraldino, a Norman noble who accompanied William, Duke of Normandy into England in 1066. He also accompanied Strongbow into Ireland in 1172, and became Earl of Desmond. He settled in Kirkcudbright and Wigtown.

Addair Spelling Variations

The frequent translations of surnames from and into Gaelic, accounts for the multitude of spelling variations found in Scottish surnames. Furthermore, the spelling of surnames was rarely consistent because medieval scribes and church officials recorded names as they sounded, rather than adhering to any specific spelling rules. The different versions of a surname, such as the inclusion of the patronymic prefix "Mac", frequently indicated a religious or Clan affiliation, or even a division of the family. Moreover, a large number of foreign names were brought into Scotland, accelerating accentuating the alterations to various surnames. The name Addair has also been spelled Adair, Odeir, Edzear, Edgar, Adare and others.

The Addair 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: Loyal au mort
Motto Translation: Faithful unto death.
