Good theory. I really don't think so. A rumour's a rumour but it would be interesting if Eira was Elaine. Where did you hear this rumour? If it is true, she would have to be Vivienne's daughter for her to be related to Morgana and Morgause, as it is strongly implied that Morgause is Gorlois' daughter.
