She was an ancestor of Diana, Princess of Wales, where the quote "There were three people in her marriage" in the promotional poster comes from.

Plot
The young Georgiana is contracted in marriage to William Cavendish, Duke of Devonshire, with the expectation that she produce his male heir. 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. William expects Georgiana to tolerate the child's presence. He also suggests that she "practise mothering" on the young girl. When Georgiana gives birth to a girl, William is displeased. 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.
Georgiana becomes a leading light in fashionable society. She socialises with the young Lady Bess Foster at Bath and invites her to live with them since Bess has nowhere else to go. William has an affair with Bess, causing Georgiana to feel robbed of her only friend and betrayed by Bess. Bess tells Georgiana that her motive is to regain her three sons (whom her husband has taken from her), so she continues to live with them.
