Filidh

The Dublin Saga, from Edward Rutherfurd's The Princes of Ireland series:

"There were three classes of learned men on the island.  The humblest were the bards, the storytellers who would entertain the company at a feast; of a higher class entirely were the filidh, guardians of the genealogies, makers of poetry, and even sometimes prophesy; but above them both, and more fearsome, were the druids."


Now I know what at least one word means!:
