Well yeah, but PAGANE might be right here. I mean, the village was probably Turkish or mixed Turkish/Bulgarian when it is built - we understand that because the name is in Turkish, and there are still Turks in the village- yet no Turks migrated to USSR. Plus, we don't know when Bulgarians settled there. In this sense, your ancestor for example might be actually from Pleven or somewhere else, then migrated to Silistra, then to Ukraine.
Although I'm not aware of an Ottoman document that shows Bulgarian presence in 1571 in the village if that's what Bulgarian registers show, then the Bulgarian settlers of the village might be indeed there since the early 1600s. In this option, this means your ancestor was in that 10% Christian part lived in the region and isolated in there. Considering isolation continued in the USSR period too, it is not much likely that you will see meaningful Bulgarian/Turkish matches from the region as long as your own community is not tested.
