Ideas?

Moonshadow has four brothers. One older brother with black eyes, who I can't think of a name for, a twin brother, with purple eyes, called Vaati, a younger brother, with green eyes, called Bramble and an even younger brother, with mother of pearl eyes, who I can't think of a name for, either. So... I was hoping some of the epic people on this spot could help me think of names for the ones I can't think of names for. Thanks, I really appreciate it! ^^
