The Tatars also did raids into Slovakia. In my dads village they came in during Mass and executed the priest and the alter servers right there. They are buried under the alter to this day. I consistently show up as having some ugro-finnic ancestry on most tests but I don’t know if that could count as asian. I think some slovaks do have some asian ancestry, I mean we’re not East slavs but even my aunt looks very mongoloid . Supposedly in Slovakia there are some villages in the mountains where haplogroup Q reaches 5 percent. If this can happen as far west as Slovakia I’m sure some east slavs have some asian too, but overall genetic studies show it to be very minute.
