Renesmee is a female name.
Renesmee is an invented name. The daughter of Bella Swan and Edward Cullen of the Twilight-Saga (Stephenie Meyer) was called Renesmee. It is a combination of Renee (Bella’s mother) and Esme (Eward’s foster-mother’s name).
There is no meaning of the name Renesmee, because it was invented. But it could mean “born again” (Renée) and “loved”, “esteemed” (Esme).
