On 2 April 1836, after a one-year engagement, and between episodes two and three of The Pickwick Papers , Dickens married Catherine Thomson Hogarth (1816–1879), the daughter of George Hogarth, editor of the Evening Chronicle .  They were married in St. Luke's Church,  Chelsea , London. After a brief honeymoon in Chalk in Kent the couple returned to lodgings at Furnival's Inn .  The first of their ten children , Charley, was born in January 1837, and a few months later the family set up home in Bloomsbury at 48 Doughty Street, London, (on which Charles had a three-year lease at £80 a year) from 25 March 1837 until December 1839.   Dickens's younger brother Frederick and Catherine's 17-year-old sister Mary, moved in with them. Dickens became very attached to Mary, and she died in his arms after a brief illness in 1837. Unusually for Dickens, as a consequence of his shock, he stopped working, and he and Kate stayed at a little farm on Hampstead Heath for a fortnight. Dickens idealised Mary- the character he fashioned after her, Rose Maylie , he found he could not now kill, as he had planned, in his fiction  and according to Ackroyd he drew on memories of her for his later descriptions of Little Nell and Florence Dombey.  His grief was so great that he was unable to meet the deadline for the June instalment of Pickwick Papers and had to cancel the Oliver Twist instalment that month as well.  The time in Hampstead was the occasion for a growing bond between Dickens and John Forster to develop and Forster soon became his unofficial business manager, and the first to read his work. 
Monks is forced by Mr. Brownlow to divulge his secrets: his real name is Edward Leeford, and he is Oliver's paternal half-brother and, although he is legitimate, he was born of a loveless marriage. Oliver's mother, Agnes, became their father's true love after Monks witnessed his parents' divorce. Mr. Brownlow has a picture of Agnes and began making inquiries when he noticed a marked resemblance between her and Oliver. Monks has spent many years searching for his father's child – not to befriend him, but to destroy him (see Henry Fielding 's Tom Jones for similar circumstances). Brownlow asks Oliver to give half his inheritance (which proves to be meagre) to Monks because he wants to give him a second chance; and Oliver, being prone to giving second chances, is more than happy to comply. Monks later moves to America, where he squanders his money, reverts to crime, and ultimately dies in prison. Fagin is arrested and condemned to the gallows. On the eve of his hanging, in an emotional scene, Oliver, accompanied by Mr. Brownlow, goes to visit the old reprobate in Newgate Prison , where Fagin's terror at being hanged has caused him to lose himself in daydreams and develop a fever.
