Need a name for my GSD female puppy?

A fitting german name would be perfect. My mother wants to name her "sura" (suh-rah); no offense to her but I think it's stupid as heck, she was insistent for a while but now she told me to find a better one. When I came with my suggestion (before she said hers) she rejected it and forgot about it. She didn't buy the dog, I adopted it after searching for weeks on the internet. Please someone tell me some fitting names for a gsd female, especially german names.
