I selected Crimean Tatars and Circassians as indigenous inhabitants for Crimea and Krasnodar Krai (with Adygea enclave) respectively, although there were some more indigenous in the past.
I don't have a lot of data for oblasts near Moscow, but since this area was originally Baltic and Finnic, i merged it with Balto-Uralic cluster, although later migrations definitely changed genetic structure, especially in the biggest cities like Moscow and Nizhny Novgorod.
