Don't Name Your Daughter Harper

A powerful word and surname, conjuring up ideas of royalty, drawbridges, and knights, Castle is currently on the up for boys in the US, though it's yet to enter the charts for girls. With recent interest in Chapel and Banks, however, and the potential for nickname Cassie, Castle doesn't seem too far-fetched. Derived from the Latin castellum, meaning "fortified place", it was given to 25 boys in a recent year, and with its connection to protection and the Disney Castle, it may just start to appeal as a girl name too.
