Interestingly, the name Nimitz doesn't sound that much Germanic, it could have been a Germanized version of an originally Slavic name like Němec. (Which would mean "German"; quite a recursion :)
The Nimitz family stems from Bremen, and quite deeply so (13th century), which would fit, because Bremen/Lueneburger Heide is not that far from territories settled by Polabian Slavs.
Oh, wow. I vaguely seem to remember that there was an aircraft carrier or other naval ship named after him. Read it somewhere long back, IIRC. Will google it, or it may be in your link.
In WW2, consider the names of the top US general in Europe and the top admiral in the Pacific.
