Congrats for your forthcoming twins :) Lemme thow in a few extra suggestions to those of my esteemed colleague Nanaea (High Priestess of the Anagram Oracle and Ayatollah of Rock 'n' Rolla).
*** Anagramming "NicoleRenee " yields "Corine Elene" and "ColeenIrene " ; *** Anagramming "RobynRoger " yields "Bryon Roger " and "RobynRoger ". Note that Robyn IS a bona fide male name too (as in noted musician Robyn Hitchcock). Another possibility is "Reborn Gyro" which I do not suggest, despite being partial to all things Greek. *** Anagramming "Andres " also yiels two interesting names, "Sander" and "Sendra".
