Comments for the name Marielle

I've seen Marielle spelled Maryelle, but the only time I saw it spelled that way was in the book called MARYELLE by Linda Ford.

I have never met anyone with the name Marielle, save for my sister. When I think of Marielle, I think of a pretty girl, who is polite and nice. Basically the opposite of my sister. But my family calls my sister Mari.
