The surname Failey is believed to have originated in Ireland. It is considered an Anglicized form of the Irish Gaelic name O'Faili or O'Failigh, which means "descendant of Failghe." The name Failghe itself is derived from the Gaelic word "fail," meaning "leader" or "chief."
The earliest recorded instances of the Failey surname can be traced back to the 12th century in County Longford, Ireland. The O'Failighs were a prominent family in the region and were among the leading septs or clans of the Ui Briuin people.
In the 16th century, during the Tudor conquest of Ireland, the Failey surname began to appear in various historical records. The Annals of the Four Masters, a chronicle of medieval Irish history, mentions a notable figure named Failghe O'Failghe, who was the Chief of Muintir Failghe in the year 1540.
One of the earliest known bearers of the Failey surname was Conall Failey, a landowner in County Longford who was recorded in the Fiants of the Tudor period, which were records of official letters and grants issued by the English Crown in Ireland.
In the 17th century, during the Cromwellian conquest of Ireland, many Irish families, including the Faileys, were displaced from their ancestral lands. Some Faileys sought refuge in other parts of Ireland, while others emigrated to other countries, such as England, Scotland, and the Americas.
