Irwen History, Family Crest & Coats of Arms
The surname Irwen was first used in the Scottish/English Borderlands by an ancient Scottish people called the Strathclyde-Britons. It was a name for someone who lived in the parish of Irving in the county of Dumfriesshire or from Irvine in Strathclyde. There are a variety of possible origins of the name and we will explore some of them here. One source claims the name was a "descendant of Erewine (sea friend); or one who came from Irvine (green river), in Ayrshire. " 
Another source postulates the name was from "Mac Heremon, 'Here-mon's Son.' Heremon was the seventh in descent from Milesius, and became monarch of all Ireland.  And another believes that Irwin was "the Irish form of Irvine. The singular Christian name Crinus, which prevails in the family of I. of Tanragoe, co. Sligo, is traditionally derived from Krynin Abethnas, the second husband of the mother of Duncan, King of Scotland." 
Early Origins of the Irwen family
The surname Irwen was first found in Ayrshire, at Irvine, a parish, in the district of Cunninghame, about 26 miles (W. S. W.) from Glasgow. "[Irvine] derives its name from the river on which it is situated, and appears to have attained a high degree of importance at a very early period. The inhabitants obtained from Alexander II. a charter conferring upon the town all the privileges of a royal burgh; and a charter confirming all previous grants was subsequently given to them by Robert Bruce, in recompense of their services during his wars with England in the reign of Edward I." 
Alternatively, the name was "from Irving, the name of an old parish in Dumfriesshire, There are many Irvings (or Irvines as most of the Dumfriesshire families spell the name) here." 
According to voice of tradition, the family descend from Duncan "the first of Eryvine," killed at the battle of Duncrub in 965. Other records show the earliest listed was William de Irwin, an armor bearer to King Robert the Bruce. He received a grant of lands encompassing the Forest of Drum, on the banks of the River Irvine. And it was here that he had Drum Castle built which would become the family seat of the Clan for centuries. The river originally was named Lar Avon, or West River.
Robert de Hirvine, ancestor of that previous William was mentioned in a Charter dated 1226 and he was at that time tenant of the Douglas Clan. From 1331-33 the family received further grants of land and by 1400 had become a very predominant family. The Chief of the Irvines lead his Clansmen in the Battle of Harlaw in 1511. Sir Alexander Irvine was slain there, and it was said of him: 'Gude Sir Alexander Irvine, The much renowned Laird of Drum.' 
"Washington Irving (1783-1859), the American author, was son of William Irving, a native of Shapinsay, Orkney."

Migration of the Irwen family to Ireland
Some of the Irwen family moved to Ireland, but this topic is not covered in this excerpt.
To escape the uncertainties and discrimination faced in Scotland, many decided to head out for North America. Once they arrived, many Scots fought with relish in the American War of Independence; some went north to Canada as United Empire Loyalists. Many ancestors of these Scots have recovered their lost national heritage in the 20th century through Clan organizations and Scottish historical societies. Among the settlers to North America were:

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: Candide et constanter
Motto Translation: Fairly and firmly.
