That she let him think he's responsible for her death when he's not? No.... Lana just knew. The writers probably told her, so that she would know what Tinker Bell was referring to. Tink said, that Regina ruined her soulmate's life.

I doubt, Regina ever knew who Marian really was. To the Evil Queen, she was just some random peasant woman who helped Snow White.
