What is the names of the two people Oliver is under the care of when he experiences a happy life?  Answer the above question based on the context below:  A young woman in labour makes her way to a parish workhouse and dies after giving birth to a boy, who is systematically named Oliver Twist by the workhouse authorities. As the years go by, Oliver and the rest of the child inmates suffer from the callous indifference of the officials in charge: beadle Mr. Bumble and matron Mrs. Corney. At the age of nine, the hungry children draw straws; Oliver loses and has to ask for a second helping of gruel ("Please sir, I want some more"). For his impudence, he is promptly apprenticed to the undertaker Mr. Sowerberry, from whom he receives somewhat better treatment. However, when another worker, Noah, maligns his dead mother, Oliver flies into a rage and attacks him, earning the orphan a whipping. Oliver runs away to London. The Artful Dodger, a skilled young pickpocket, notices him and takes him to Fagin, an old Jew who trains children to be pickpockets. Fagin sends Oliver to watch and learn as the Dodger and another boy try to rob Mr. Brownlow, a rich, elderly gentleman. Their attempt is detected, but it is Oliver who is chased through the streets by a mob and arrested. A witness clears him. Mr. Brownlow takes a liking to the boy, and gives him a home. Oliver experiences the kind of happy life he has never had before, under the care of Mr. Brownlow and the loving housekeeper, Mrs. Bedwin. Meanwhile, Fagin is visited by the mysterious Monks, who has a strong interest in Oliver. He sends Monks to Bumble and Mrs. Corney (now Bumble's domineering wife); Monks buys from them the only thing that can identify Oliver's parentage, a locket containing his mother's portrait.
