What is the russian meaning of the name Dounia?

I need to know what Dounia means in Russian for a project on the meaning of names for the novel Crime and Punishment. HELP!|||It is the diminutive of Avdotya, the Russian form of Eudocia (meaning "to seem well").|||There is no meaning at all. Can only write to you that Dounya is a short form of another russian name - Eudokia, which means, when translated from Greek, Goodwill. Hope, that helps.
