Thats highly interesting!!!!
years ago I've met his grandson.
Old Army LtCol Arnold Teubner survived WW2 and lived at least until the 60ies/70ies.
His son Achim joined the Navy and became Commander. KIA in 1945, had a great part in sinking the "HMS Glorious" in WW2.
His grandson Joachim joined the German Air Force and became a LtCol too. Retired around 2002.

So 3 Generations, in 3 different branches, all reached the same rank :-)
Have to look, if I still have some pics somewhere.
Best,
