Coco- hmm. Not a great baby name, fab stripper name though. I knew a grown-up who renamed herself Coco by deed poll. She had a chanel obsession. Came across as somewhat tacky and 'try-hard'
Ava- (you said 'honest' sorry!!) is too Myleene Klass. The correct pronunciation of Eva in most of the world is Ava, and I like it better this way, in fact I love it pronounced Ava and spelt Eva. Reason mainly that Ava is too Avian flu and celebbed out.
Im not horrified by your names though they are nice
