The name Ferry in Ireland is derived from the native Gaelic O'Fearadhaigh sept that was located in County Donegal. The variant Fairy is also associated with this Gaelic sept and these names can today be mostly found in Donegal and Sligo.

Origen: Escocés. First found in Lanarkshire, where they held a family seat at Rutherglen from early times, some say before the Norman Conquest in 1066. An ancient couplet says "nae man can tell, nae man has seen, when the Faries Haena in Ruglen been." To translate this couplet means that no man can remember when there hasn't been a family of Faries at Rutherglen.

Variantes: Fairie, Fairrie, Farie, Fairey, Ferry, Ferrie, Fairy, Faireye y otros.
