Surname Gannon - Meaning and Origin

Gannon: What does the surname Gannon mean?

The surname Gannon is of Irish origin, derived from the Gaelic name "Mag Fhionnáin," which means "descendant of Fionnán.” The name 'Fionnán' itself comes from the Gaelic word "fionn," meaning "fair," frequently indicating a light-haired person. Therefore, the name might have been provided to the progenitors of the Gannon families due to them being fair-haired or of fair complexion. It emphasizes the physical characteristics of the family's ancestors. The Gannon families are primarily found in the west of Ireland, particularly in the county of Roscommon. Like many Irish names, Gannon was widely spread beyond Ireland due to mass emigration during the time of the Great Famine in the mid-nineteenth century. Today, it is found both in its original form and in a variety of anglicised spellings all around the world.

Gannon: Where does the name Gannon come from?

The surname Gannon is believed to have originated from Gaelic Irish culture, derived from the Gaelic word "Mag Fhionnain", which translates to the "son of Fair Child." Thus the surname was given to the descendants of someone fair-haired or fair-skinned. Many Gannons in history have hailed from the Galway and Rosscommon counties of Ireland.

While Gannon is still common in Ireland today, it has also become widespread in English-speaking countries such as the United States, Australia, and England, often due to Irish immigration throughout history. The highest concentration of Gannons can be found in the United States, and more specifically in the state of New York. While the surname is not among the most common, it is still prevalent with around 12,000 individuals holding the Gannon surname in the US and approximately 5,000 in Ireland.
