Plan a roots trip to French Southern Territories

Remote French territories with sparse settlement and unique colonial heritage.

← All countries

The French Southern Territories comprise several island groups and territories in the southern Indian Ocean and Antarctic region, including Réunion, Mayotte, the Kerguelen Islands, Crozet Islands, Saint Paul and Amsterdam Islands, and the Terre Adélie sector of Antarctica. These territories have varying degrees of European settlement and administrative infrastructure. Families with roots in these territories often have connections to French colonial administration, military service, or trading posts. Records are typically held in French archives or local government offices, with earlier documents sometimes microfilmed or digitised by the Archives de France.

Terre Adélie is claimed by France but also subject to Antarctic Treaty provisions; family records from this territory are extremely rare.

Genealogy highlights

  • Civil registration (état civil) records from 19th century onward for inhabited islands, maintained locally and centrally in France
  • Colonial administrative records documenting settlement, employment, and transfers of officials and their families
  • Military service records, as many territories were garrison posts or penal colonies
  • Marriage and birth records often cross-reference metropolitan France due to repatriation and transfers
  • Limited census data; most genealogical reconstruction relies on civil registration and church records

Record types to know

  • Civil registration (état civil)
  • Colonial administrative archives
  • Military service records
  • Church and parish records
  • Naturalization and residence permits

Heritage trip tips

  • Réunion and Mayotte have established tourism infrastructure; other islands have severely restricted access or no civilian settlement
  • Verify current travel permits and entry requirements well in advance, as regulations vary by territory
  • French is the primary language; English is spoken in limited areas
  • Visit local mairies (town halls) and archives during business hours; advance contact by email or post is advised
  • Plan visits during austral spring or summer (October–April) for best accessibility and weather

Practical notes

  • Most genealogical records for these territories are held by the Archives de France (nationales and departmentales) rather than locally
  • Réunion and Mayotte are overseas departments with full French civil registration; smaller territories have minimal or no civilian population
  • Request records by post or online inquiry; in-person visits to remote islands require special permission and are rarely possible for tourists
  • Many 19th-century records have been digitised through FranceArchives or regional library partnerships
