Aunt is out of names?

My aunt is pregnant for the sixth time. It's a funny story, really. Her husbands name is Arthor, her name is Gweneveeve, but she recently decided to go by Ginny. Can you see where I'm going? Her first kid was a girl, she named her Molly. Next she had twins, whom she named Fred and George. Then Bill and Charlie. Her next set if twins, which she's pregnant with now, are going to be Ron and Percy. But it turns out, it's triplets. And she's out of Weasleys to name then after. I was thinking she should expand to other Harry Potter characters. What do you all think? (the last triplet is a girl, by the way)
