Georgiana becomes a leading light in fashionable society. In his mind, he has fulfilled his obligations to her as her husband but, by failing to provide him with a legitimate male heir, she has failed in her obligations as his wife. When Georgiana gives birth to a girl, William is displeased. He also suggests that she "practise mothering" on the young girl.

William expects Georgiana to tolerate the child's presence. Georgiana is quickly disillusioned by her husband, especially when Charlotte, an illegitimate child fathered by William whose mother has died, comes to live with them while Georgiana is pregnant. The young Georgiana is contracted in marriage to William Cavendish, Duke of Devonshire, with the expectation that she produce his male heir.
