I saw a tm for apparel in the same city as this names whois, made me think you had a tm on it. Same first name but different last. You, family or know them?
I think it should be viewed as a brandable. Which means it may not be easy to sell, because there aren't hundreds of obvious potential buyers. But to the right end user it could sell in the 4-figure range.
Perhaps the .de holder might want it.
I think blitz means lightning in German, blitzen could be plural.
Research the TMs if any.
