McGaffin History, Family Crest & Coats of Arms
The ancient Scottish name McGaffin is carried by the descendents of the Pictish people. It was a name for a metalworker. The Gaelic form of the name is Mac Ghobhainn, which means son of the smith. 
Early Origins of the McGaffin family
The surname McGaffin was first found in Inverness-shire (Gaelic: Siorrachd Inbhir Nis) divided between the present day Scottish Council Areas of Highland and Western Isles, and consisting of a large northern mainland area and various island areas off the west coast, the shire was anciently both a Pictish and Norwegian stronghold, where the name is from the Gaelic 'Govha' meaning 'a blacksmith' and as such could have been a name that applied to people throughout Scotland.
However, as in the case of clans like the Fletchers or Clarks, eventually the name became attributed to a specific area or region. As such, The Clan was also located in Nithsfield in the 12th century, and recorded as a Border Clan. To the west in Elgin and Galloway they were known as the MacGavins. Due to the Anglicization of the Gaelic name, spellings were often widely different.
"MacGowan (McGowan) is the name of an old Stirling family. Gilcallum McGoun had a precept of remission for rapine and other crimes on the lands of the abbot of Cupar, 1503 (RSS., I, 953).

"In the reign of David II there was a Clan M'Gowan, probably located somewhere on the river Nith, whose chiefship was adjudged to Donald Edzear (RMS., I, App II, 982). This Edzear was a descendant of Dunegal of Stranith (Nithsdale), whose seat was at Morton, Dumfriesshire, about the beginning of the twelfth century. The name here may indicate descent from Owen the Bald (the Eugenius Calvin of Simeon of Durham), king of the Strathclyde Britons, who was killed in 1018."

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: Juncta arma decori
Motto Translation: Arms united to merit.
