Early Origins of the Cunniff family

The surname Cunniff was first found in Connacht (Irish: Connachta, (land of the) descendants of Conn), where they held a family seat as chiefs of their name. Irish history was greatly influenced by the Norman invasion of 1172, and thereafter, the surnames of Irish Gaelic clanns and septs and many of the Norman families became almost indistinguishable. This family name was found later in Leitrim.
