Teague is an uncommon, yet historic given name of Irish origin. It's derived from the Old Irish 'Tadhg,' which means 'poet' or 'dreamy.' The name was borne by several early Irish saints and chieftains, most notably, Saint Teague of Galway, who is said to have founded the city in the 15th century.
"Over time, the name Teague saw significant fluctuations in popularity, with peaks of 82 births in 2006 and drops to as low as 7 births between 1983 and 1985. From the late 1990s onwards, it became more stable, oscillating between roughly 20 to 60 births per year."
