Meaning

What does Kieran mean?

The name Kieran originated from the Irish Gaelic name Ciarán, which is derived from the word "ciar" meaning "black" or "dark featured". This name has its roots in ancient Celtic culture and is believed to date back to the 5th century AD.

Kieran was a popular name among early Irish saints and religious figures. One of the most notable was St. Ciarán of Saigir, who lived in the 6th century and founded the monastery of Seir-Kieran in County Offaly, Ireland.

During the Medieval period, the name Kieran was also associated with prominent figures in Scotland. Kieran of Dull, a Scottish saint who lived in the 7th century, was known for founding a church in Dull, Perthshire.
