What are the names of the three ghosts in Charles Dicken's 'A Christmas Carol'?

They are Jacob Marley, The Ghost of Christmas Past, The Ghost of Christmas Present and The Ghost of Christmas Yet To Come.

The first ghost is Jacob Marley, Scrooge's late business partner, warning him of continuing in miserly ways. Second, the Ghost of Christmas Past, who showed him how he used to be warm and generous and how he has changed into a mean and miserly man. Third, the Ghost of Christmas Present shows him that in the homes of both Bob Cratchit and Scrooge's nephew Fred, he is toasted in goodwill and affection (by most people). He explains how want and ignorance will destroy society if we do not learn to care for each other. Fourth, the Ghost of Christmas Yet to Come takes Scrooge to a vision of how he will die.
