Re: Last name on the list is not likely to be Russian
Bulgarian? I think you think so because there is a Bulgarian artist of the same name
No. I just happen to have some ancestry of both and fluence in both languages. That is NOT a Russian family name and it is the only name which is given in a Name + Family Name notation as used by Bulgarians today(*) and not in Name + Paternal Name + Family Name as used by Russians.
While there is some likelihood that someone from that clan has ended up in USSR during the let's say Komintern era, that is less likely than someone from Bulgaria proper.
(*)Bulgarians also used to use a similar notation, but with different grammar resulting in different way of writing out the Paternal middle name (finish with ov, not with ovich or ovna)
