Réamann is a masculine Irish name derived from the Old Norse name 'Hreiðmarr,' which entered Irish nomenclature during the Viking era. The name combines elements meaning 'counsel' or 'protection' and 'famous' or 'renowned.' In modern Irish usage, Réamann (sometimes anglicized as Raymond) maintains its cultural significance while being relatively uncommon. The accent over the 'e' (fada) indicates a longer vowel sound in Irish pronunciation. Though not among the most popular Irish names, Réamann represents a proud connection to Ireland's Norse-influenced heritage. It appeals to parents seeking a distinctive name with authentic Celtic roots and historical depth.
