I think you got the name right. As I understand it he was a cousin of the red baron. While A pilot he was also largely responsible for developing the logistics for the invasion of Russia.
I am listening to a book on tape it is a collection of interviews from 4 German aces Kapinski and Galand so far. Kapinski mentioned what a brilliant job he did. They didn't anticipate the invasion lasting through the winter....
Oops I cant mention this next part as it will be the subject of my quiz when I get a chance.
Needless to say there were gallant pilots on both sides of the battles.
