This short article describes some of the archival materials held at Shulbrede Priory, located in West Sussex, England. This private home in Haslemere also serves as an archive containing materials related to the Ponsonby family and presents exciting research opportunities for historians of early twentieth-century Britain. The collection includes material related to the composer Hubert Parry and the diaries of Arthur and Dorothea Ponsonby. Additionally, it contains manuscript and photographic materials related to the Ponsonby's daughter, Elizabeth—particularly her involvement with the so-called Bright Young People of the 1920s and 1930s. As it remains a private home, this archive also compels us to think about the nature of family histories.
