Prince Arnulf of Bavaria

[Kalafrana]

I am currently reading a biography of Heinrich Himmler. It turns out that this deeply unpleasant individual came from a solid professional middle class family, and at the time of his birth in 1900 his father was tutor to the sons of Prince Arnulf of Bavaria. In fact, one of them, Prince Heinrich, was young Himmler's godfather. Apparently, Himmler senior left shortly afterwards and pursued a career as a headmaster, but Prince Arnulf's family kept in touch. Prince Heinrich was killed in WW1 at the age of 32.

Does anyone know anything about these Wittelsbachs?
