Really? :D I guess if someone could pull off Guillermo they can pull Gwenfrewi off. GwenMelisande sounds really cool... with Gwenfrewi as a nickname like you said. Thank you so much! :)
Trust me I've grown up with people with far more cumbersome names than Gwenfrewi. Kanapeethani, Pooja (all three of them) being examples. I just prefer the look and sound of Gwen to Gwenfrewi personally.
