MacClaffy History, Family Crest & Coats of Arms

The surname MacClaffy comes from the Irish name Mac Laithimh, from "flaitheamh" meaning "ruler." In Ulster the name is anglicized as MacClave and MacLave. In County Monaghan, however, the name is frequently mistranslated as Hand, since the name is phonetically similar to another Gaelic word "lamh" for "hand." Claffey is the most common variant in the midlands of Ireland. [1]
