Frederick Bullock
Frederick Bullock delays marrying Maria Osborne in hopes of getting more money from her father. Delighted over George's disinheritance, Frederick hopes his Maria will be worth more now.
Jane Osborne
She once had a budding romance with an artist, but her father smashed that, ending Jane's only chance for life, although she hopes Dobbin may be getting romantic when he tries to tell her of George's marriage. Old Osborne makes her a slave, but through her, Georgy comes to live in Russell Square. Georgy makes her old age happy. Neither of the Osborne sisters has ever thought Amelia worthy of their brother George.
John Sedley
Father of Joseph and Amelia, John Sedley is a British merchant who loves practical jokes. He gets Rebecca to eat curry, and while her mouth is afire, Joseph offers her a chili, which she thinks must be cold, but, of course, isn't. Sedley teases her about liking things from India, referring to her play for Joseph. He prefers Becky as a daughter-in-law to some native girl Jos might bring home.
John Sedley has little patience with Joseph's airs, but in his old age, he wants Joseph near. After his financial ruin, Mr. Sedley imposes on Amelia. Joseph, too indifferent for imposition, furnishes money but won't involve himself in his father's dubious wine venture.
The one argument that makes Sedley consent to Amelia's marriage is that old Osborne will be furious. Before his death, he apologizes to Amelia for his and his wife's unfairness to her. Old Sedley dies in poverty.
Mrs. John Sedley
At first a kind, good-natured woman eager to keep her place in Vanity Fair, she loses her good temperament with the onset of poverty. Critical of Amelia's love for Georgy, she quarrels with her daughter. However, in her final illness she enjoys Amelia's constant devotion and care.
