What Delaney means
Delaney means descendant of the dark one of the Slaney. The Irish joins a word for black to a river name, so the second half is geography rather than a quality.
Where Delaney comes from
Delaney anglicizes the Irish Ó Dubhshláine — dubh, black or dark, joined to Sláine, the River Slaney in Leinster. The commonly repeated dark challenger reading takes the second element for a word meaning defiance, which the river name is not. A separate Norman French de l'aunaie, of the alder grove, is also proposed and would make some bearers French rather than Irish. Its use as a given name is American and modern.
