    FORAN is the Anglicized form of the Gaelic (Irish) name ‘O’Fuarthain, O’Fuarain’, meaning ‘descendant of Fuar(th)an’, a personal name believed to be derived from the Gaelic ‘fuar’, cold. The name was first Anglicized as O’Forhane and Forahan, these forms being used mostly in County Kerry and West Cork. The first recorded spelling of the family name is shown to be that of O Foirtchern, which was dated 1175, Annals of the Four Masters, during the reign of Rory O’Connor, High King of Ireland, 1166-1175. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to “develop” often leading to astonishing variants of the original spelling.
