It's great that you're interested in the origins and history of the surname Dulaney.
The name Dulaney
originally appeared in Gaelic as Dubhshlainte. The word 'dubh' means black, and Slaine is topographical; it is Anglicized as Slaney, and may refer to the river Slaney. The name was first found in Leinster, where they held a family seat from very ancient times, some say well before the Norman Conquest and the arrival of Duke William at Hastings in 1066 A.D.
Many spelling variations of the surname Dulaney can be found in the archives. One reason for these variations is that ancient scribes and church officials recorded names as they were pronounced, often resulting in a single person being recorded under several different spellings. The different spellings that were found include Delaney, Delany, Delane, Delaune, Dalaney and others.
