The short answer is that Bronwyn is a misspelling of Branwen

My Richards dictionary thiks Bran is a "Crow" much less grand than a raven.
Breast is far mor near the mark I would say, and it seems to be spelled OK
the way it is. Except the gender bit, But it means "Lesser Celandine" as
well, according to Richards and they may not be so sexy.
