Frage an Karl Theodor von und zu Guttenberg von Arnd H. bezüglich Gesellschaftspolitik, soziale Gruppen

Sehr geehrter Herr KARL-THEODOR FREIHERR ZU GUTTENBERG
Folgende Vorstellung Ihrer Person und Familie zu einem Konvent in Amerika 2007 ist im net zu finden
" Baron zu Guttenberg is a member of the German Parliament (CSU) and Chairman of the CSU’s Committee on Foreign Affairs. In Berlin he serves as Department Spokesman for the CDU/CSU Parliamentary Group on the Foreign Affairs Committee and as Spokesman for Non-Proliferation and Arms Control.
Before being elected into Parliament, he was head of the Guttenberg family’s companies in Munich and Berlin, and gained work experience in Frankfurt and New York. Baron zu Guttenberg was Managing Director of the Guttenberg GmbH (Munich) and is a member on several boards. Prior to this position, he studied law and completed a doctoral thesis on comparative constitutional law (JD).
Guttenberg has published many articles on foreign and European policy as well as on the period between 1933 and 1945 in Germany. (His family was actively involved in the resistance against Hitler.)"
Für mich ist der letzte Teil von Interesse. War Ihre Familie im Widerstand aktiv? Mich würden Quellen hierzu interessieren.
Danke für die Auskunft
