Regan is one of a triad of three haggard witches, modelled on the witches from Macbeth. the other two are named Goneril and Cordelia (after King Lear's daughters). They foretell that Edmund shall become king, despite him referring to them as "hideous crones", "loathsome drabs" and "snaggle-toothed vultures".
It is only after he leaves that they realise they've mixed him up with Henry Tudor (i.e. the genuine Macbeth). They appear to make this mistake frequently.
