Thank you for your explanation.
I didn't think it is something personal. I thought that maybe it can clarify what Herga means, or from where it comes from. I always wanted to know what my surname means, but I never could find out anything about it.
It's really interesting that it's roman.
I'm from Croatia, and that's my grandmothers maiden name. She thougth it's a name of german origin.
I don't know anything about it really.
