Delaney Name Meaning
English (of Norman origin): habitational name for someone from any of various minor places in northern France named from Old French aunaie ‘alder grove’. Irish: Anglicized form, influenced by the Norman name, of Gaelic Ó Dubhshláine ‘descendant of Dubhshláine’, a personal name composed of the elements dubh ‘black’ + slán ‘challenge’, ‘defiance’. MacLysaght, however, suggests that this element may be from the Sláinge river.
