Today's Irish surnames are underpinned by a multitude of rich histories. The name De laune 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 surname De laune 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.
