Fennessey History, Family Crest & Coats of Arms
The Fennessey surname is an Anglicized form of the Gaelic Ó Fionnghusa, "descendant of Fionnghus," a personal name composed of the elements "fionn," meaning "fair," or "white," and "gus," meaning "vigor," or "force."
Early Origins of the Fennessey family
The surname Fennessey was first found in Tipperary (Irish: Thiobraid Árann), established in the 13th century in South-central Ireland, in the province of Munster, where they held a family seat as chiefs seated at Cashel of the Kings in that county. Irish history, after the Norman Conquest of England, was strongly influenced by the invasion of Strongbow in 1172, almost equal to the enormous Irish cultural impact on England Scotland, Wales and the whole of Europe before the Norman Conquest from the 1st to 7th centuries. Many Irish clanns and sept names were intermixed and family groupings became almost indistinguishable. This family name was found later in the county of Waterford.

The Fennessey Motto +
The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Recte adhibito Deus adjuvat
Motto Translation: God will help us to do right
