The name Fahy is O'Fathaigh in Gaelic, and probably originates from the word fothadh which means base or foundation. Another rarer English version of the name is Vahey and occasionally Fay, which has a different root except for occasional instances in Galway.
The name Green has been used as a synonym for Fahy, but this is believed to be another good example of the not uncommon absurd mistranslation of Irish names into English. A green or lawn in Gaelic is faithche, pronounced fahy.
Fahy, also spelt Fahey, is almost exlusively a Galway name, though it is also found in the neighboring County Tipperary.

The name is still plentiful in the region and there is a village in the vicinity of Loughrea called Fahysville.

The Fahy Institute in that country was founded to commemorate his life.
