Finlandese siberiano

I had no idea there were villages in Siberia habited by Finnish people. I know there are people who speak similar language to Finnish but I had no idea there is also Finnish people. Looks like they were Finnish who were sent to gulags and later released.

Though, it seems the language has disapeared together with the villages as the older population died away.
