In our research across France, we consult a wide array of historical sources, ranging from parish registers to civil records. Baptisms, marriages, burials, and confirmations were recorded in Catholic and Protestant churches — primarily in Latin until the French Revolution. After 1792, civil records replaced religious registries, introducing more standardized and informative documentation kept in French and overseen by local municipal authorities. These documents typically include names of parents, occupations, witnesses, and occasionally details on place of origin, migration, or residence, as well as specific local events. Church and civil records remain the foundation of genealogical research, but are often supported by notarial archives, inheritance documents, marriage contracts, and local legal proceedings. In border regions historically affected by foreign rule, records may also appear in German, Spanish, or Italian, depending on the period and jurisdiction. The volume and continuity of such sources allow for deep and rich reconstructions of ancestral narratives, spanning multiple generations and offering insight into both personal, social, cultural, and regional histories.
