I believe it has already been pointed out, but an apostrophy is the worst idea you could have had. Many, many official systems don't do them, but she will have to give her correct name, or they won't accept it. What does she do in the car registry? Or on her passport?
I know you are probably not reading this anymore, and the milk has apparently already been spilled. I guess you will find out. Except of course, you won't, because it is her problem now.
I actually find the name very beautifull, it sounds great and has a nice flow. And you can hope that no one recognises it's origin. Because honestly? As cool as it is to be a nerd, and I really believe that, most people don't.
You did not "ruin her life". That's bullshit. But don't be surprised when she uses those exact words when she's fifteen. But then again, she might do that for any reason anyway, just as she could be bullied for any reason.
I just hope you know what to tell her when she asks.
Because I have a weird name as well, and I have thought my parents selfish for choosing it because it "sounded nice and was unusual", though I have come to like it over time.
