I love
Rowena pronounced "ro-WEN-uh" but dislike it pronounced "ro-WEEN-uh." Rowen and Wennie (
Winnie) are sweet nns too. I think it's only subject to teasing when pronounced with the "WEEN" part.
I didn't even think about
Harry Potter but then again I'm really not all that familiar with HP characters - never read the books and have only seen the first 3 movies
