Delaney is an Irish surname derived from the Gaelic Ó Dubhsláine, Dubh meaning black and Slaine for the River Slaine (Slaney). DeLaney is also of Norman origin. There is a branch of Dulaneys in the United States who trace back to a Thomas Delany. Thomas's son, Daniel, claimed to have been descended from Dr. Gideon Delaune, a Huguenot physician and theologian and founder of the Apothecaries' Hall. Hence, there are multiple discussions among genealogical circles as to the origin of Delaney since it can be anglicized Gaelic or anglicized French.

The River Slaney was named after the Norman knights who moved through Ireland from 1167-1185 to fight on behalf of removed king of Leinster Dermot MacMurrough who was forcibly exiled by a confederation of Irish forces under the new king, Ruaidrí Ua Conchobair. DeSlaney (Of Slaney) became the family name of the Norman family which were given land along the River Slaine (Slaney). The Norman Lord of Slaney wore black armour and used a black sword in battle.[1][2]

Over time a few names derived from the names DeLaney and Ó Dubhsláine including Delaney, Delany and Dulaney.
