The meaning of Hefferon

Irish: 1. Anglicized form of Gaelic Ó hÉimhrín ‘descendant of Éimhrín’, a diminutive of the legendary personal name Éimhear (still in use as the female personal name Emer). This is the name of a prominent Mayo family. The e vowel of the first syllable distinguishes it from Havron, which arises from Ó hAmhráin. 2. Anglicized form of Gaelic Ó hUidhrín ‘descendant of Uidhrín’, a personal name from a diminutive of odhar ‘dun, sallow, swarthy’. Compare McGivern, in which the dh of Uidhrín has also been Anglicized by a bilabial rather than a dental fricative. Where the fricative is lost there has been some confusion with Hearn. There may also have been some confusion with Heffernan.
