Meet little Renesmee!  In fact, meet 110 of them.  Nancy from Nancy’s Baby Names has a few reasons why this is a poor choice.

Renesmee is rather inelegant, isn’t it? Yes, it is. It’s the baby name equivalent of a car crash, in fact. Stephenie Meyer at the wheel, taking out innocent bystanders Renée and Esmé. If you like the sounds in the name, untangle it and simply use Renée Esmé or Esmé Renée … Is the name of a fictitious vampire/human hybrid baby in a poorly written YA book really more important to you than, say, a family name? I hope not.

There’s also the whole “I’m practically a grown man but am cosmically fated to get it on with your baby” thing.  So, she’ll have that going for her.
