The Federal Republic of Germany

Could the mother of the Father Land be Prussia? Were Ancestors to 'Mother Prussia' on the Baltic Sea before Slav or Celt saw that sea? If Prussia was mother to Germany, could the father have been the Holy Roman Empire? I need these family affairs explained to me.

What do I think I know about Germans? They:
~ sometimes read my posts;
~ politically many support a Green Party platform;
~ celebrate their culture;
~ are interested in business, like designing and selling BMWs;
