I may have found an additional Ukrainian in a Generals-rank.
Here are buried among other commanders of the Ukrainian struggle for freedom -- The Genenerals
He was the chairman of the Ukrainian Helsinki Group. (Or is this the more correct Helsinki Watch Group of the post WWII years???
One the other side Hryhorenko sounds like:
2.) Mg. Stab/Russisches Schutzkorps in Serbien
Generalmajor Kipryjenko, I.
2.) Kdt Brigade/Russisches Schutzkorps in Serbien

Čačewadze, Dotik [this is the correct writing in German papers; and he is not a count/prince]
Fürst Čawčewadze, Spiridon [this is the correct writing in German papers; and he is a count/prince]
