Well, I think the term you may be looking for is either Sióga or Sídhe. The word "Fey" is not actually Gaelic in origin, although people in Scotland and Ireland do sometimes use it. It comes from the Old English word "fæge," meaning "fated." The word itself is often used as a general term to describe the widely varying immortal beings populating myth and folklore. (It can, however, also mean "crazy.") Fun fact: this is why the word "fairy" is supposed to be offensive to the Good Folk; while "fey" means simply "fated," "fairy" means "ill-fate," and goes back to a time when everything from failed crops to epidemics was blamed on the immortals.
The Irish word for the Fey in general is Sióga (singular: Sióg) while another word, Aos Sídhe (or simply Sídhe), is used to describe the highest-ranking (and most powerful) subrace of Fey. (These are direct descendants of the Tuatha de Danann.) However, those two words are sometimes used interchangeably. I hope that helps!
