Well here is a puzzle for you to think about.We not only have Lacy but Lacey and De Lacey names as well and as it was custom in those days when people could not write or even spell correctly.That the name could be misspelt an carried down in generations changing again and again. If you look up the Coat of Arms book for England you will find the Lacy begins in Ireland and originated in Limerick.Of Norman/Irish origin.Coat of Arms is Gold with a Red Lion. The Crest has a Gold Eagle and the Moto is "Meritis Augentur Honores". Also the Lacy name is connected to The Earl of Essex who married a Lacy and he is the Uncle of Robin Hood I belive. So does the name begin in France as originally suspected or does it come from Ireland?
