What does Cieran mean?
The name Cieran originates from the Irish Gaelic language and is a variant spelling of the name Ciaran. Its origins can be traced back to the 5th century in Ireland, where it is derived from the Old Irish word "ciar," meaning "dark" or "black," potentially referring to hair color or complexion.
Cieran has its roots in early Irish Christianity and is associated with Saint Ciaran of Saigir, a prominent Irish saint and monastic founder who lived from around 512 to 588 AD.
