The claim that Natalia Naryshkina was from a Russian noble family of Tatar origin may refer to an interpretation or speculation based on distant roots. It is possible that very old or indirect links with Tatars existed, but this does not mean that Natalia Naryshkina herself was considered to have Tatar origins.
The idea that Natalia Naryshkina, the mother of Peter the Great, had Tatar origins or came from the Tatar nobility is a rumor without solid historical basis.
