Delaney comes from the Irish surname Ó Dubhshláine — meaning "descendant of Dubhshláine" (the dark challenger; dubh = dark, sláine = defiance or challenge).
Delaney entered the U.S. top 1000 as a girls' name in 1993 and has been climbing steadily. Today it sits in the U.S. top 350.
Delaney reduces to eight — the number of inherited resolve.
