I have a few anangrams to add to Nanaea and Pavlos's very impressive suggestions. Some are anangrams, but some are not. If it's a Boy/Girl set of twins, I like "Robyn Colleen" for the girl, and "Robert Collin" for the boy. Other names I like are "Leo" and "Leonora", "Clayton" and "Cleo". I hope all of our suggestions lead you in some sort of direction towards the right names.
