Bryn is an up-and-coming gentle, yet substantial, Welsh name that would also be effective in the middle spot. In Wales it's more often heard as a boys' name.
Bryn entered the US girls' popularity list in 1999 and is now at Number 745. Alternate spelling Brynn has outshone it, ranking last year at Number 190.
Reality star Bethany Frankel named her daughter Bryn in 2010.
The attractive Bryn, well used for boys in Wales, sounds rather feminine here; There were only 7 boys named Bryn and 6 more given the Brynn spelling in the most recent year counted, versus over 350 female Bryns and more than 1600 Brynns. Bryn does have a history as a male name in the U.S. though; there is a college football quarterback named Bryn Renner.
