This sub-collection contains material relating to Paul Oppé's family, in particular his wife, Valentine, and his two children, Armide and Denys, but also his mother, Pauline, and his brother, Henry (known as Harry).
The majority of the material in this section of the Archive consists of correspondence received by various Oppé family members. Occasionally the content of these letters offers insight into Oppé's life and work - this can mostly be found in the large amount of letters from Oppé himself and occasional letters from various family friends that were connected to the arts - but mostly this material captures other themes which relate to the social history of the first half of the twentieth century. These themes include the First and Second World Wars, classical music and musicians, women's history, maternity, domestic staff, health, upper class and aristocratic society and private schools.
Aside from the material which relates to individuals, there is some legal and genealogical documentation of births, deaths and marriages in the family, covering Oppé's parents' generation down through to his that of his grandchildren. There is also material relating to wills, estates and properties which relates to inheritances from the Oppé and Jaffé families.
The material also includes a large amount of photographs of the family.
