The surname De lacy comes from the place name Lassi, in the department of Calvados in Normandy.
A multitude of spelling variations characterize Norman surnames. Many variations occurred because Old and Middle English lacked any definite spelling rules. The introduction of Norman French to England also had a pronounced effect, as did the court languages of Latin and French. Therefore, one person was often referred to by several different spellings in a single lifetime. The various spellings include Lacey, Lacy, Lassey, Lassy, de Lacey, de Lacy and others.
