Rowan -- a strong surname and nature name (it's a tree with red berries)-- is deservedly growing in popularity. Some scholars identify Rowan as originally a girl's name, related to Rowena and Rhonwen, while others say Rowan's always been used for both genders. Sharon Stone chose the Roan spelling, which also relates to the reddish color, for her son, while Brooke Shields used Rowan for her daughter.
Probably the most prominent bearer of the name is Rowan Atkinson, the British comic actor first seen on the sitcom Blackadder, but even better known for his Mr. Bean persona.
The name of a tree with red berries commonly found in Scotland (and said to ward off witches), some scholars say this name has been used for girls as well as boys since the Middle Ages, though no Rowans are found outside literature until modern times. In the U.S., it was almost unheard of as a girl's name before Brooke Shields chose it for her daughter in 2003, now shows great promise as an appealing Celtic choice.
