1.) Which CW general named his eldest son "Lincoln"?
2.) There was another general who named his son "Lincoln", but he denied an offer to take over a command. You will stump the German if you name him!
Note: According to my source, these were the only ones. I will double-check your guesses, but this was even for one of the sought-after quite difficult. Thus for replies goes AFAIK (and if you are very sure about another one I'll be willing to believe you).
