The name Brynn is a girl's name of Welsh origin meaning "hill". Brynn is ranked #294 on our popularity charts and is often added to lists like Pixar Baby Names and discussed in our forums with posts like "Baby a Day".
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.
