The story of Caolán

Caolán comes from the Irish caol, meaning slender, narrow or fine, with the small ending -án. It is an old name, going back to Old Irish, and it has several English spellings, including Kealan, Keelan and Kelan.

In Irish the “ao” is said like the “ee” in “see”, which is why many people say KEE-lawn. KAY-lawn is also common, and both are heard in Ireland.

The name first reached the Irish list in 1982. The CSO did not record fadas before 2018, and it now counts Caolán and Caolan separately. Its best year was 2023, when 63 boys were given one of the two spellings. The fada spelling is now the more common one, with 41 of the 56 boys in 2025. The name has long been more popular in Northern Ireland, where it was as high as 28th in 1997.
