From the experts:
Brynn outshines the original Welsh Bryn in the popularity stakes. This simple, brisk name might be seen as a combination of Bree and Lynn, an androgynous-sounding choice that especially in this spelling is not truly unisex: Brynn, for boys, is not even in the Top 1000. Other variations trendy now include Brynna, Brynnan, and Brynnley spelled many different ways.
