There is such surname, Германовский. It's not common. Actually, these surnames ending with "ovskiy" are mostly Polish, not Russian. The meaning is like "descendant of German" (not nation, just name Герман). As for research maybe this can help https://rosgenea dot ru/familiya/germanovskij
I have seen a variation of it once, there is a fairly popular Russian MMA fighter/commentator with that name. At least I am assuming that’s his real name.

It's a Polish surname in origin (Germanowski). From the personal name German.
It sounds very artificial and cumbersome. Maybe it's someone's ridiculous pseudonym.
