Mac an Fhailghigh

Mac an Fhailghigh (modern Irish orthography: Mac an Fhailí, lit. 'son of the poor man') was the name of a County Mayo and County Roscommon Irish family, according to Woulfe, of Norman origin.[1] It derives from failgheach, a Gaelic name of uncertain meaning,[2] but generally translated as 'poor man' (in the sense of a vow of poverty or a hermit).[3] The earliest form of the name can be traced back to the eponymous progenitor of the family, who came to Ireland with Strongbow in the 12th century Anglo-Norman invasion.

Anglicised variations of the name include Nally, Canally, Manally, McAnally,[1] McEnally,[1] McInally,[1] and McNally.[1]
