I can't find the origin of my family name, what else can I do?

Question:

I can't find the origin of my family name, what else can I do?

I've googled Radnitch, and even tried Radnich, but I can't find ANYthing on the origin of the name, where can I find this out? I don't speak to my family enough to ask any of them.

My family business has nothing to do with anyone else, we didn't talk for personal reasons, they are still a part of me. Thanks for your judgement.
