The name Bronwen is a girl's name of Welsh origin meaning "white breast". Bronwen and is often added to lists like British Girl Names and discussed in our forums with posts like "Octuplet Game - Girls!".
From the experts:
Bronwen is widespread in Wales, but still rare enough here to sound somewhat exotic--we think Bronwen is a real winner. (Note: the Bronwyn spelling is strictly for males in its native land.)
Bronwen Morgan is the lovely heroine of the classic novel and movie How Green Was My Valley. In Welsh mythology, Bronwen was the daughter of Llyr, the god of the sea.
Close cousin Branwen appears in Welsh medieval literature as a tragic figure who was turned into a bird. The ancient Welsh worshipped her as goddess of the moon and love.
