Looking at it, I never would've guessed it'd be a variation of
Karen. I was struggling to pronounce it in my head, but had settled on CAI-ren or cai-REN. Either way, pretty odd and yeah, the spelling makes it look too creative for me.
Also, the ren part made me assume it was a boy's name. But maybe that's just me.
Nice meaning though, you're right. Other names that mean beloved:
ahuva
AmyCananCaraCaramia (so pretty!)
Charity Frigg (who would've thunk?!)
