Personally, I love the name
Hermione. I even named my cat
Hermione. Granted, the sixth Potter book had come out the Friday before, I love the name. Even though I first heard the name because of the Potter series, I associate it more with
Hermione Gingold and
Winter's Tale. And going back to my cat being named
Hermione, people are always saying "Oh, you like
Harry Potter, then? After all, you've named your cat after one of the characters." But like others have said, in a few years, the
Harry Potter craze will die down and people will feel like they can use the names again without getting persecuted.
