I don't really understand the issue of repeat 'names' either way. But it's been accepted as Roza so I don't intend to change it. I like it that way. 
Besides, in nearly every single culture worldwide, and almost every fantasy or science fiction series has their own set of names and sometimes they're repeated throughout history. It's not a stretch for two human girls from opposite sides of the world to have similar names.
