The Clennon 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 Clennon family

The surname Clennon was first found in Ayrshire where their history vitally is enmeshed with that of the larger Logan Clan. The Clennon 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.
