Meaning and origin of the Clancy last name
Meaning of the Clancy last name: son of Flannchadh ("red warrior"). Clancy comes from the Gaelic Mac Fhlannchaidh, son of Flannchadh, a name meaning red warrior. The Clancys of County Clare were hereditary lawyers, known as brehons, to the O'Brien lords. A curious detail: a second Clancy family in Leitrim had no link to the Clare family, so the same name grew up twice in different parts of Ireland.
