From Tadhg to Teaghan
The story of Teaghan
Tadhg was among the most common Irish men's names for centuries, borne by kings and by the hereditary poets who were a formal institution in Gaelic society — a trained professional class with legal status, whose praise and satire mattered politically. The name's ubiquity produced the generic use: Tadhg an mhargaidh for the ordinary man, and in English the anglicized Teague was used, often contemptuously, for an Irishman generally. The diminutive Tadhgán gave the surname Teegan and the modern given name Teagan, which crossed to America in the 1990s and is now used mostly for girls. Teaghan peaks in 2011.
Meaning
Irish "poet", with a diminutive
From Tadhg, an Irish name generally read as a poet or philosopher, with the diminutive ending -án giving Tadhgán. Teagan and Teaghan are anglicizations. Tadhg is pronounced tyge, and the gh in the modern English spelling is a decorative addition rather than a survival of the Irish. The name is used for both sexes in America.
