Pemberley
Pemberley is the fictional country estate owned by Fitzwilliam Darcy, the male protagonist in Jane Austen's novel "Pride and Prejudice". It is located near the fictional town of Lambton, and believed by some to be based on Chatsworth House, near Bakewell in Derbyshire.
Clare Darcy
Clare Darcy was the pseudonym used by the American novelist Mary Deasy (1914–1978) for her Regency Romance novels, i.e., novels set in Regency England. She was born on May 20, 1914 in Cincinnati, Ohio, and died in Ohio in May 1978. A number of the manuscripts of her Regency novels (as well as of her other works), along with notebooks, scrapbooks, photographs, correspondence, book reviews, etc., are in the collection of the Howard Gottlieb Archival Research Center at Boston University, whose website (see link below) provides further information about the Deasy/Darcy collection.
