Quinn jumped because of Glee's popularity. I like Quinn for a girl, but it's a shame that it's gotten trendy.Bentley got super-trendy because of the rabid popularity of the show 16 and Pregnant, which features a baby with this name.
Thanks. I'm not very familiar with Glee, so I didn't know there was a character named Quinn on the show. Claudia also posted about 16 and Pregnant below. I didn't think that was a very popular series, but I apparently know very little about what's on television right now.
