Surname Glennon - Meaning and Origin

all surnames with 'G'

Glennon: What does the surname Glennon mean?

The last name Glennon is of Irish origin, deriving from the Gaelic term "O'Glionain," which means "descendant of the fierce one." This surname was originally prominent in rural Connacht as well as in Counties Meath, Fermanagh and Roscommon.

The Glennon family is thought to have been descended from a powerful 6th century chieftain named Glionan, who is said to have been a fierce battle leader. In 889, the family were driven from their holdings in Connacht and eventually settled in Fermanagh. They continued to live in this area for over 800 years, maintaining their family home and their hereditary titles until The Flight of the Earls in 1607.

The Glennon surname is still found throughout Ireland today, with the greatest concentration of Glennons living in County Fermanagh, where the family originally settled. In modern times, this surname has spread to many other countries as families have emigrated around the world.

The Glennon family is known for its strong sense of heritage and identity, and although the current clan may no longer live in the same area as they did historically, they still acknowledge their unique roots and proud shared history. The fact that so many people with this surname remain in Ireland is a testament to the success and longevity of a family name that has been passed down from generation to generation.
