History of the Lacey name

The de Lacys were among the greatest of the Anglo-Norman conquerors: Hugh de Lacy received the entire kingdom of Meath from Henry II in 1172 and built the mighty castle of Trim, while his son became Earl of Ulster. The medieval earldoms faded, but the name endured, and in Wexford, where Laceys have long been numerous, it also absorbed a native surname, Ó Laitheasa. Continental branches won extraordinary fame: Peter Lacy of Limerick became a field marshal of Russia, and his son Franz Moritz von Lacy a field marshal of Austria. Lacey remains well known in Leinster and Munster today.
