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. Yet another increasingly popular spelling is Rowen.
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.
In 2014, the gender split for Rowan was running 2 to 1, boys over girls.
