Teagan

Teagan is the transferred use of an Irish surname, an anglicized form of the Gaelic Ó Tadhgáin meaning "descendent of Tadhgán". The personal name Tadhgán is a diminutive of “tadhg” which is an Old Irish word for a “poet, storyteller” (poets and storytellers played an integral role in early Celtic societies). For instance, we know Tadg was the first name of an 11th century king of Connacht (a medieval province in western Ireland). First a clan name, Ó Tadhgáin eventually morphed into the last name Teagan. Parents in the United States recently hijacked Teagan as a first name – originally used for girls and eventually becoming unisex. For baby girls, Teagan was likely inspired by names like Reagan or Meagan. Inspiration also came from the surname craze in the United States (the trendy usage of surnames as forenames). There are several other Irish surnames on the U.S. charts today such as Sullivan, Finnegan, and Keegan. Teagan seemed like a natural follower. However, Teagan is not to be confused with Tegan, a female name with different Celtic roots (Tegan is Welsh, not Irish).
