Early Origins of the McIlrath family

The surname McIlrath 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

The descendants of the Dalriadan families who made the great crossing of the Atlantic still dot communities along the east coast of the United States and Canada. In the American War of Independence, many of the settlers traveled north to Canada as United Empire Loyalists. Clan societies and highland games have allowed Canadian and American families of Scottish descent to recover much of their lost heritage.

The McIlrath 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.
