a charitable figure is a parallel to that of the miser. Douglas-Fairhurst sees that the minor character Gabriel Grub from The Pickwick Papers was also an influence when creating Scrooge. It is possible that Scrooge's name came from a tombstone Dickens had seen on a visit to Edinburgh. The grave was for Ebenezer Lennox Scroggie, whose job was given as a meal man—a corn merchant; Dickens misread the inscription as "mean man". This theory has been described as "a probable Dickens hoax" for which "[n]o one could find any corroborating evidence". When Dickens was young he lived near a tradesman's premises with the sign "Goodge and Marney", which may have provided the name for Scrooge's former business partner. For the chained Marley, Dickens drew on his memory of a visit to the Western Penitentiary in Pittsburgh, Pennsylvania, in March 1842, where he saw—and was affected by seeing—fettered prisoners. For the character Tiny Tim, Dickens used his nephew Henry, a disabled boy who was five at the time A Christmas Carol was written. The two figures of Want and Ignorance, sheltering in the robes of the Ghost of Christmas Present, were inspired by the children Dickens had seen on his visit to a ragged school in the East End of London. Themes The transformation of Scrooge is central to the story. Davis considers Scrooge to be "a protean figure always in process of reformation"; Kelly writes that the transformation is reflected in the description of Scrooge, who begins as a two-dimensional character, but who then grows into one who "possess[es] an emotional depth [and] a regret for lost opportunities". Some writers, including Grace Moore, the Dickens scholar, consider that there is a Christian theme running through A Christmas Carol, and that the novella should be seen as an allegory of the Christian concept of redemption. Dickens's biographer, Claire Tomalin, sees the conversion of Scrooge as carrying the Christian message that "even the worst of sinners may repent and become a good man". Dickens's attitudes towards organised religion were complex; he based his beliefs and principles on the New Testament. Dickens's statement that Marley "had no bowels" is a reference to the "bowels of compassion" mentioned in the First Epistle of John, the reason for his eternal damnation. Other writers, including Kelly, consider that Dickens put forward a "secular vision of this sacred holiday". The Dickens scholar John O. Jordan argues that
