The lacey family appears to have originally lived in the settlement of Lassy in the region called Calvados in northern France. The name of this place is derived from the Gaulish personal name Lascius, which is of uncertain origin, and the local suffix -acum. The Gaelic form of the surname lacey is de Lis. However, there is a native Irish family of County Wexford named O Laitheasa who anglicize their surname as lacey. This name, which was originally O Flaithgheasa, is derived from the Gaelic word flaith, which means prince.
