My father was from Cheljabinsk and mother's family were from Kyiv.

My mother's name is Naталья Оставівна Золотова. Zolotova to me is russian I think but I have no clue about her origins to be honest.
-ов(а) is a Russian ending for a name. Although there are lots of people in Ukraine with such names, they are not Ukrainian in origin.
