Marriage records in New South Wales (NSW) are crucial for genealogical research, documenting unions from the early colonial period to the present. Civil registration began in 1856, but church records date back to the early 19th century, covering Anglican, Catholic, and other denominations. These records typically include names, ages, birthplaces, occupations, and parents’ details, helping researchers trace family connections. The NSW Registry of Births, Deaths & Marriages maintains official records, with historical indexes available online. Newspapers, church registers, and archival sources also provide valuable marriage information. These records are essential for uncovering ancestry and verifying family history in NSW.
