Show ContentsGuiler History, Family Crest & Coats of Arms

The first family to use the name Guiler lived in the ancient Scottish kingdom of Dalriada. It was used as a nickname for a young man with tanned skin or with tawny hair with darker streaks. The Gaelic form of the name is Mac 'Ille riabhaich, which means son of the brindled lad. 1

Early Origins of the Guiler family

The surname Guiler was first found in Ayrshire (Gaelic: Siorrachd Inbhir Àir), formerly a county in the southwestern Strathclyde region of Scotland, that today makes up the Council Areas of South, East, and North Ayrshire, where they held a family seat from very early times.

However, the name "is common in Galloway and throughout the Highlands, and was a common personal name in Rreadalbane 200 and more years ago. A money allowance was granted for Andrew, son of John Make Gille Reue, a Scots hostage who died in Carlisle prison in 1300. Thomas M'Gilrewy was a Douglas tenant in the barony of Buittle, 1376, and David McKilwirk (i.e. Mcilwrick) was bailie of Dumfries, 1476. Donald Makgillereoch or Mak-gillereacht appears as witness in 1485 and 1497, and Robert Makgillereach was concerned in the 'spulyie of Kilravock,' 1497. Duncan McGiilereach in Fandownyach had a precept of remission for offences committed by him, 1503, and the obit of Johannes M'Gillerawyth in Glenloquhacy is recorded in 1506. Michae Dow Mcalgerache, an aged Highlander, was convicted of common theft and 'pikry' (petty theft) in Kirkcudbright in 1508 and banished the town." 1

Migration of the Guiler family

Significant portions of the populations of both the United States and Canada are still made up of the ancestors of Dalriadan families. Some of those in Canada originally settled the United States, but went north as United Empire Loyalists in the American War of Independence. The late 19th and early 20th centuries saw the ancestors of many Scots on both sides of the border begin to recover their collective national heritage through Clan societies and highland games. Some of the first North American settlers carried this name or one of its variants: John McIllreavy landed in Philadelphia, Pennsylvania in 1846; Archibald McIllree landed there in 1832; William McIlrea landed in Philadelphia in 1834.

The Guiler 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.
