The ancient Dalriadan kingdom consisted of the Hebrides islands, and the rugged mountains of Scotland west coast. The name McIlwrath began in this region; it was 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 McIlwrath family

The surname McIlwrath 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

McIlwrath 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, McIlwrath has been spelled Macilreach, McIlreach, MacIlreath, McIlreath, Macilriach, McIlriach, Macilraith, McIlraith, Macilaraith, McIlaraith, Macilarith, McIlarith, Macilwraith, McIlwraith, Macilwraithe, McIlwraithe, MacIlwrathe, McIlwrathe, MacKilwrath, McKilwrath, MacKilwrathe, McKilwrathe, Macgfillreich, McFillreich, Macileriach, McIleriach, Macillrich, McIllrich, Macilurick, McIlurick, Macilwrick, McIlwrick, MacIlwrith, McIlwrith, MacIlrevie, McIlrevie, MacKilreve, McKilreve, MacKilrea, McKilrea, MacElrath, McElrath, MacElreath, McElreath, McElvrick, MacElvrick, McIllrie, MacIllrie, MacAlwraith, McAlwraith, Revie, McRevie and many more.

United States McIlwrath migration to the United States +

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 McIlwrath were among these contributors, for they have been located in early North American records:

The McIlwrath 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.
