Question: Thomas Bertram is a supporting character in which of Jane Austen's novels?
Context: Jane Austen lived her entire life as part of a family located socially and economically on the lower fringes of the English gentry.  The Rev. George Austen and Cassandra Leigh, Jane Austen's parents, lived in Steventon, Hampshire, where Rev. Austen was the rector of the Anglican parish from 1765 until 1801.  Jane Austen's immediate family was large and close-knit.  She had six brothers—James, George, Charles, Francis, Henry, and Edward—and a beloved older sister, Cassandra.  Austen's brother Edward was adopted by Thomas and Elizabeth Knight and eventually inherited their estates at Godmersham, Kent, and Chawton, Hampshire.  In 1801, Rev. Austen retired from the ministry and moved his family to Bath, Somerset.  He died in 1805 and for the next four years, Jane, Cassandra, and their mother lived first in rented quarters and then in Southampton where they shared a house with Frank Austen's family.  During these unsettled years, they spent much time visiting various branches of the family.  In 1809, Jane, Cassandra, and their mother moved permanently into a large "cottage" in Chawton village that was part of Edward's nearby estate.  Austen lived at Chawton until she moved to Winchester for medical treatment shortly before her death in 1817. Jane Austen fan fiction is the collection of numerous sequels and spin-offs produced by authors who have either used the plot of Austen's original novels, or have extended them, to produce new works of fiction.  Austen's posthumous popularity has inspired fan fiction that runs the gamut through numerous genres, but the most concentrated medium has remained the novel.  According to Pucci and Thompson in their 2003 survey on the contemporary evolution of Jane Austen's work, at the turn of the 20th century (over 150 years after the final publication of her first collected works), over one hundred sequels, rewritings, and continuations of her novels had been published. Old Friends and New Fancies: An Imaginary Sequel to the Novels of Jane Austen (1913) is a novel by Sybil G. Brinton that is generally acknowledged to be the first sequel to the works of Jane Austen and as such the first piece of Austen fan fiction.  It incorporates characters from each of Austen's six major novels into one unified story, alongside characters of Brinton's own invention.  Keeping to the spirit of the source novels, its major theme is the difficulties faced by assorted pairs of lovers placed within the class structure of early 19th century Britain. Thomas Bertram is a supporting character in Jane Austen's 1814 novel, Mansfield Park.  He is the elder son and heir of Sir Thomas Bertram, a baronet and wealthy landowner in Northamptonshire, who also owns an estate in Antigua. Mr. James Rushworth is a character from Jane Austen's "Mansfield Park".  "Mansfield Park" is a novel about a young girl, Fanny Price, who goes to live with her wealthy relatives, the Bertrams.  The novel follows the familial life and social circle of the Bertrams.  Rushworth is part of this circle.  He is the son of Mrs. Rushworth and has inherited Sotherton Estate, an estate of about seven hundred acres.  He has 12,000 pounds a year, which makes him a very eligible bachelor.  He is the fiance of Maria Bertram who is the eldest daughter of Sir Thomas Bertram. Mansfield Park is the third published novel by Jane Austen, first published in 1814.  The novel tells the story of Fanny Price starting when her overburdened family sends her at age 10 to live in the household of her wealthy aunt and uncle, through to her marriage.

A Memoir of Jane Austen is a biography of the novelist Jane Austen (1775–1817) published in 1869 by her nephew James Edward Austen-Leigh.  A second edition was published in 1871 which included previously unpublished Jane Austen writings.  A family project, the biography was written by James Edward Austen-Leigh but owed much to the recollections of Jane Austen's many relatives.  However, it was the decisions of her close friend and sister, Cassandra Austen, to destroy many of Jane's letters after her death that shaped the material available for the biography. Mansfield Park is a 1983 British television drama serial, made by the BBC, and adapted from Jane Austen's novel of the same name, originally published in 1814.  The serial was the first screen adaptation of the novel.  Contrary to Patricia Rozema's later movie adaption, it is faithful to Jane Austen's novel.  Jonny Lee Miller, who has a small role as Charles Price in this serial, played Edmund Bertram in the aforementioned film version of the novel.
