Find old friends, only with Minecraft names?

I played Minecraft with a friend from elementary school, but we fell apart because we went to different schools. I can't write to him because he hasn't been on for a year. I've already tried most of it. Names googled etc. I wanted to get in contact with him again but currently only have his MC name (and real one, of course)

Take a look at DasÖrtliche if you can find what you are looking for.

Ne doesn't find anything, but thanks anyway
