the person from the paper slip is not Maximilan but Robert von Trutzschler (originally: Robert Franz Oswald Adolph von Trützschler auf Falkenstein). He ist also called „Baron Bertie von Trutzschler“ in some documents. He was born in Grossenbehringen on Mai, 24th, 1876. In the 1890ies he lived in Berlin/Lichterfelde, the place of the „Haupt-Kadetten-Anstalt“ of the German (Prussian) Armee. That makes me believe he got his military education there.
Baron Bertie Trutzschler got married in Nantwich, Cheshire, England on Sept., 13., 1906 to Catarine („Kitty“) Murphy. They got four children, amongst them Maximilan, born in 1910.
Baron Bertie Trutschler kept all his life in England and died there in Gorstella, Kinneron, on February 14th, 1940..
I am interested in the biographie of his son, Maximilian, who was a Britsh subject but also served in the German army. Maximilian was captured in Russia and the Soviets kept him in a P.O.W. camp in Russia until 1950. Just a few months after he came free and back to England he emigrated, together with his mother and his divorced sister Mafalda von Kalckreuth to Tanzania or South Africa. He was still alive when his mother died in 1962. I would be interested in more details about his life in Africa, especially when and where he died.
