Cahir

Cahir along with its traditional spelling Cathair is well-used in modern Ireland. Now it's finding a wider audience thanks to The Witcher , though Cahir is the main villain of the series. It was in the US charts from 2017 to 2020, but fewer than 5 baby boys were named Cahir in the US in 2021, suggesting that the effect on parents was short-lived.

Pronounced KAH-hir.

As of October 2026, Cahir ranked #12346 in US births in 2025 SSA, peaked at #9907 in 2019.
