Fedelm is Irish in Origin.

Fedelm is an early Irish (Old Irish) feminine given name from the Goidelic branch of Celtic. It is well attested in medieval literature of the Ulster Cycle, notably borne by Fedelm the seer in the Táin Bó Cúailnge and by figures such as Fedelm Noíchrothach and Fedelm Foltcháin. The etymology is debated and likely native Celtic rather than Latin; its resemblance to Latin fidelis is coincidental. Scholars have proposed connections with ideas of “seeing/knowledge” or “beauty,” but no consensus exists, so the meaning is generally listed as unknown.

Usage was strong in early medieval Ireland, later waned, and re-emerged in modern times through the forms Fedelma and especially Fidelma, which gained wider notice via the Sister Fidelma novels. Documented variants include Fedelm, Feidelm, Fedelma, and Fidelma. Do not confuse it with the separate masculine names Feidlimid/Feidhlim (anglicized Felim). Diminutives are rare.
