Real names are NOT allowed on Most Sites or allowed to be reported, either.
Besides Lena (Elena) is the Stage Name, that the Site of Young-Goddess decided to give that Model. WebMasters, Modeling Agencies, Content Providers, and Production Companies can name a Model (Gal) any Name they decide to name her. It's NOT the Model's choice......that is why there are so many Aliases for one Model.
None of us here can even give you any other Names this Model may be known as without a Pic being Posted here. Why don't you include a Picture of this Lena (Elena)???
