I have a friend with a daughter named Re'Elle. While I like the name, I am not sure about the spelling. It took me awhile to get used to when she was a baby. The mom had liked the name Gabrielle and the dad didn't, but both liked the ending of it, so they came up with Re'Elle's name. I think she (she is 11 now) likes to have her name shortened to Re sometimes.
They came up with the spelling because they wanted to be sure people could pronounce it correctly.
