The surname larrison was first found in County Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland in the province of Connacht, where they held a family seat as chiefs descended from the great Hy Fiachrach, a group of tribes claiming descent from King Niall of the Nine Hostages. 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 EnglandScotland, Wales and the whole of Europe before the Norman Conquest from the 1st to 7th centuries. Many Irish clanns, sept names were intermixed and family groupings became almost indistinguishable. The Larrissey also branched to Kilkenny.
