In my opinion, Renae looks better than the original Renee. It is more unique as I have met 2 or 3 Renees but never a Renae, so if you want to give your child a name that's unique but normal, elegant but cool, use Renae.
Renae Lawrence (b. 1977) is a former panel beater and caterer from Newcastle, New South Wales. She is the only female among the nine arrested as part of the Bali Nine group of nine Australians found guilty of attempting to carry a total of 8.3 kg of heroin from Indonesia to Australia.
She is currently serving a 20-year sentence in an Indonesian prison.
Ew, this totally and completely ruins a perfectly good name. Renee isn't that common in the first place, so don't say you're trying to be "unique" by spelling it this way! It takes out all the French beauty of the name and leaves American tackiness in its place.
