Family name origins & meanings
- English : occupational name for a deacon, or perhaps more probably for his servant. In Middle English two forms coalesced: deakne, from Old English, and diacne, from Old French. Both are ultimately from Late Latin diaconus, from Greek diakonos ‘servant’.
- Irish : when not of English origin; it was taken to Ireland in the 17th century, it may be an Anglicized form of Gaelic Ó Deocáin ‘descendant of Deocán’, a personal name of uncertain derivation and meaning.
