Olwyn is a popular Welsh name that might be an alternative to the more familiar Bronwen or Rhonwen -- though in Wales the female form is usually spelled -wen and the male one -wyn.

There are several Percivals scattered through the Harry Potter series, which might help transform the old-fangled, fussy image it has accrued.

Persephone is the esoteric name of the Greek mythological daughter of Zeus by Demeter, the queen of the harvest.

Popular in Wales, but likely to be mispronounced as Ryan here.

Most of the notable Rivers have been male, but this nature name certainly flows as well for a girl. The name River is still rising for both genders, with about 3500 baby boys receiving the name last year vs. 1900 baby girls.
