What is the name of Lady Catherine de Bourgh's daughter?

Lady Catherine de Bourgh's daughter is Anne de Bourgh. Anne lives with her mother at Rosings Park in Kent and is presented as a sickly, sheltered young woman whose future has been planned largely by Lady Catherine.

Lady Catherine expects Anne to marry her cousin, Mr. Darcy, because such a marriage would unite the Darcy and de Bourgh estates. She speaks of this intended match as though it were already settled, but Darcy has no obligation to accept it. Anne herself has very little dialogue and remains a largely passive presence in the novel.

Anne is sometimes confused with other women connected to the central families. Charlotte Lucas becomes Mrs. Collins, Jane Bennet is Elizabeth's elder sister, and Elizabeth Bennet is the heroine who eventually marries Darcy. Anne de Bourgh is Darcy's cousin through his mother, Lady Anne Darcy, and is also the daughter of the formidable Lady Catherine.
