Where did 'Azuza' come from- are you thinking 'Azusa', like one of the current crop of location-names?
While I wouldn't go so far as Sweden and outlaw really unusual names, it does bring to mind all those hippie-kids like Zowie Bowie and Free (Carradine, wasn't it?) who changed their names to more 'normal' ones... I am of mixed feelings. An ususual but attractive name can be cutting edge, and start a trend (OT-believe it or not, my 25th place 'Sam' had people around here going '*Sam*? How- different.'), but as much as I would've gotten to enjoy getting totally creative, I was concerned that the name #1) fit the child, & #2) be ok to live with. I save my naming acts of superlative creation for fiction, & video game characters, lol.
PS Cloverleaf, I like 'Helix'! And the unusual names y'all mentioned- 'Coltrane', 'Aya', 'Cairo' etc are all pretty cool & I can't imagine causing any kid anything but joy. But y'all know what I'm talkin' about. If you send your kid to public school (I don't, hehe, so I guess I could've gotten freaky!), there is some responsibilty (#1, to teach kids not to make fun of other kids' names, of course, but we can't police every kid) to 'fit in'.
