I don't think of
Bridget as retro, I know or have known several Bridgets around who would be age 19-25 about now. I definitely think it could grow in popularity some day, it's a Br- name which is fairly popular of late, but it's different from the frillier and trendier ones around now.
Hester I'm not sure about. I like it alot, but I think since
Esther seems to be slowly gaining in popularity and
Hester can't be too far behind her.
Bridget Peronel is my favorite
Bridget combo so I have to suggest it.
