The story of Ferdia

Ferdia is a modern spelling of Fer Diad, also written Ferdiad. What the name means is unclear. It has been read as “man of smoke”, “man of the pair” and “man of two feet”, and it may even have come from the place name Áth Fhir Diad rather than the other way round.

In the Ulster Cycle Ferdia is a warrior who fights for Connacht. He and Cú Chulainn trained in arms together under Scáthach and were foster-brothers and close friends. The two were equal in every feat, except that only Cú Chulainn knew the Gáe Bolga, and only Ferdia had a skin of horn that no weapon could pierce. In the Táin Bó Cúailnge they meet at a ford and fight for days, until Cú Chulainn uses the spear and kills him. The ford is Áth Fhir Diad, Ardee in Co. Louth, where a bronze statue of the pair now stands.

Ferdia reached the CSO lists in 1984 and has stayed a rare choice. Its best rank was number 205 in 1993, and 11 boys were named Ferdia in 2025.
