This might be one of my favorite names ever. I knew a girl with this name but her parents chose the spelling “Raizel” instead of Raisel. Her nickname was Hazel because it rhymed with it, I loved that so much.
There are many spellings of this name, and in fact, Raisel is one of the less common ones. I have seen Raizel (most common), Reyzl (mine), Reyzel, Reyzle.
