Alderney's records were mostly destroyed during the Second World War, but Family History Volunteers have compiled all of the available records, both civil (except censuses) and ecclesiastical, and have contacted those persons who could provide further information. Several hundred families in various regions of the island, with genealogies tracing to the 1800s, have been categorized as old Alderney families, Breakwater families and others, with family names of Duplain, Gaudion, Hougez, Le Vallée, Ollivier, Pezet, Audoire, Batiste, Barbenson and Renier, Le Cocq, Le Mesurier, Sebire and Simon. As the island was re-surveyed after the German occupation, no land records are available for the period before 1945, although baptism registers since 1662 have been located from several sources.
