The McGlennon surname is an Anglicized form of Gaelic Mac Gille Fhinneain, a patronymic name created from a Gaelic personal name "Fionnán," from the Gaelic "fionn," meaning "white."

Early Origins of the McGlennon family

The surname McGlennon was first found in Ayrshire where their history vitally is enmeshed with that of the larger Logan Clan. The McGlennon spelling of this name was first found in Druimdeurfait, in Ross-shire, where they were a branch of the Highland Logans, who lived along Loch Lochy. According to family lore, they descend from Gilliegorm, Chief of the northern Logans, who was killed battling the Clan Fraser. His pregnant wife taken captive by Lord Lovat. Her son, born humped back, was called Crotair MacGilliegorm, the "crooked-back son of Gilliegorm." Fearing future revenge on the Frasers by the boy, he was sent to a monastery at Beauly, where he became a monk. He was said to be an ardent follower of the Irish Saint Fhinan, and one of his children took the name Mac Gillie Fhinan, which eventually became MacLennan.

United States McGlennon migration to the United States +

Many settled along the east coast of what would become the United States and Canada. As the American War of Independence broke out, those who remained loyal to the crown went north to Canada as United Empire Loyalists. The ancestors of all of these hardy Dalriadan-Scottish settlers began to recover their collective history in the 20th century with the advent of the vibrant culture fostered by highland games and Clan societies in North America. Highland games, clan societies, and other organizations generated much renewed interest in Scottish heritage in the 20th century. The McGlennon were among the earliest of the Scottish settlers as immigration passenger lists have shown:

The McGlennon 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: Hoc majorum virtus
Motto Translation: This is the valour of my ancestors.
