Etymology of Naismorthay

What does the name Naismorthay mean?

The surname Naismorthay is thought to be an occupational name for a maker of knives or nails, deriving from the Old English "cnif," meaning "knife," or "noegel," meaning "nail" combined with "smith." 1

One source notes, the name is derived from "Nail-smith; but they bear two broken hammers in their Arms, as if the name were No smith !" 2

Naismorthay Coat of Arms Creation

In his autobiography, James Nasmyth, the engineer, tells that in the reign of James III. of Scotland the Earl of Douglas was a rebel, and crossed from England determined to resist the Royal power. He was met by the Earl of Angus, the Maxwells, the Johnstones, and the Scotts. In one of the encounters with them Douglas was victorious, and an ancestor of the Nasmyths, who fought for the King, took refuge in a village smithy. The smith offered him protection, dis-guised him as a hammerman with a leathern apron, and asked him to lend a hand at his work.

While thus at work, several of the Douglas followers entered the smithy. The disguised hammerman saw that they suspected him, and in his agitation struck a false blow with his sledgehammer and broke the shaft in two. On seeing this, one of the pursuers rushed at him, calling out, " Ye're nae smyth." The hammerman turned upon his assailant, and, wrenching a dagger from him, speedily overpowered him. The smith also helped to drive out the Douglas men. A party of the King's soldiers appeared, Nasymth rallied them, and turned defeat into victory. For this he got a grant of lands, and as armorial bearings he took a right hand with a dagger between two broken hammer shafts. The motto was, " Non arte sed marte " (Not by art but by war): Since then the motto has been reversed, and stands " Non marte sed arte," and instead of the broken hammer shafts there is the device of the famous Nasmyth steam hammer. 3

Early Origins of the Naismorthay family

The surname Naismorthay was first found in Renfrewshire (Gaelic: Siorrachd Rinn Friù), a historic county of Scotland, today encompassing the Council Areas of Renfrew, East Renfrewshire, and Iverclyde, in the Strathclyde region of southwestern Scotland, where they held a family seat from early times and their first records appeared on the early census rolls taken by the early Kings of Scotland to determine the rate of taxation of their subjects. 4

"Adam Nasmith, owner of lands at Brechin, died before 1420. The Nasmyths were an old family of burgesses at Hamilton. James Nasmytht, witness in Glasgow, 1543. George Nasmyth was one of those hanged for holding Paisley against the king and his regent, 1565, and John Nesmyt is mentioned by Moysie as one of those concerned in a conspiracy in Holyrood, 27 December 1591. There was a resignation of property in favor of Robert Nasmyth in Glasgow, 1552." 4

Further to the south in England, Hugh Nasmith was listed in Yorkshire in 1277. 5

And it is here in England that we find definitive proof of the former spellings of the family. Roger Knifsmith was listed in London 1246-1289; Adam Knyfsmith in the Assize Rolls for Lancashire in 1285; Saman le Knyfsmyth in Devon in 1310; William Knysmyt in the Assize Rolls for Staffordshire in 1326; and Robert Knysmithe was listed in 1594. 5

Naismorthay Spelling Variations

Early Notables of the Naismorthay family

John Nasmith or Naysmith (d. 1619?), Scottish "surgeon to James VI of Scotland and I of England, was second son of Michael Naesmith of Posso, Peeblesshire, and Elizabeth Baird. The family trace their descent to a stalwart knight, who while in attendance on Alexander III was unable to repair his armour, but so atoned for his lack of skill as a smith by his bravery in the fight that after its conclusion he was knighted by the king with the remark that, although ‘he was nae smith, he was a brave gentleman.’ Sir Michael, who was chamberlain to the Archbishop of...

Migration of the Naismorthay family

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: James Nesmith, who settled in New Hampshire in 1718; as well as John Nesmith, who settled in Maryland in 1747.



The Naismorthay 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: Non arte sed marte
Motto Translation: Not by science but by war.
