The story of Muireann

Muireann is the modern spelling of the Old Irish name Muirenn. It is usually explained as “sea-white” or “fair sea”, from muir (sea) and find (white, fair). That is the traditional reading rather than a proven one, as the main references say little about where the name comes from.

It was a real name in early Ireland, not a modern invention. The annals record several abbesses of Kildare called Muirenn between the 8th and 10th centuries, and a queen of Brega of the name who died in 748. Today it is carried by the broadcaster Muireann O’Connell and the Kerry singer and flute player Muireann Nic Amhlaoibh, among others.

Muireann has been given in Ireland every year since 1965. Its best year was 2011, with 81 girls and a place at number 87. It has eased since, and in 2025 it was number 196 on the CSO list, with 22 girls. It is rarer in Northern Ireland, where its highest place was 181st, in 2021.
