A little German history question...

So, I tried to find out more about the now-extinct German town of Rockenfeld - (Wiki, in German).  However, all search results are in German.  What I want to find out is when and how it was destroyed. And who were the people who lived there prior to the destruction?  Were they Germanics, Jews, Huguenots, Calvinists...?

Anyone who can help, it would be nice, thanks!
