Fiannah is English, Gaelic, Irish in Origin.
Fiannah is a modern, rare feminine name most plausibly shaped by Irish Gaelic influences. It sits between Fianna - the legendary warrior bands of Irish myth linked to Fionn mac Cumhaill - and Fiona, the Scottish Gaelic name derived from fionn “fair, white, blessed.” The added -h is an ornamental English spelling that doesn’t change pronunciation (commonly fee-AH-nuh) but echoes the look of other Gaelic-influenced names. As a contemporary invention, Fiannah blends the heroic resonance of Fianna with the soft, international appeal of Fiona.
Usage records suggest Fiannah emerges in the 21st century as a creative variant, while Fianna and Fiona have earlier and broader footprints (Fiona spread widely in the 20th century). Meaning is read through its roots: associations with “warrior band” from Irish lore and “fair/white” from fionn. Related forms and variants include Fianna, Fiana, Fiona, Fionna, and the nickname Fia.
Fiannah doesn't appear in any of the birth registries or name datasets we track. It's the kind of name that tends to be rare, regional, or newly made up. Whatever the reason, hardly anyone else has it.
