The surname Cahal was first found in County Kerry and Tipperary as there are at least two distinct septs of the name. The first sept from County Kerry descend from the Heremon line of kings and were known as the Cahills of Connaught. The second sept claim descent from  the Ir line of kings and were located at Corkashinny, or the parish of Templemore, Tipperary. This line further branched to the eponymous Ballycahill, Tipperary. Both branches descended from O'Connors, the Kings of Connacht, specifically "Cathal," also known as Conor na Luinge Luaithe, when anglicized means "Conor, the Swifter-Sailing Ship" which may elude to the seafaring coat of arms used by the family.
