Brittany and the Nantes country

Rennes, Nantes, Brest, Quimper, Saint-Malo. Which empire held this ground in which years — and, the part that matters, which archive that means.

939–1532 Duchy of Brittany no registers survive

Before the royal register ordinances of 1539 and 1579. The duchy is dated from about 939, after Alan II's victory over the Vikings at Trans-la-Forêt on 1 August 939, and the War of Succession was fought from 1341 to 1364.

The union with France is dated 1532 (the Estates of Brittany proclaimed it) or 13 August 1547, depending on the source. Baptism registers date from the ordinance of 1539, marriage and burial registers from 1579, and from 1667 registers were kept in duplicate, one copy going to the bailiwick court clerk.

In 1790 the province was divided into five departments: Côtes-du-Nord, Finistère, Ille-et-Vilaine, Loire-Inférieure and Morbihan. Civil registration passed to the municipalities by the decree of 20 September 1792. From 1793 Brittany was a centre of royalist and Catholic resistance (the Chouannerie), and Loire-Inférieure lay within the Vendée war.

The department archives are the filing unit. Côtes-du-Nord became Côtes-d'Armor later, and Loire-Inférieure was renamed Loire-Atlantique in 1957, so Nantes records may be catalogued under either name.

Brittany was invaded in 1940 and freed after Operation Cobra in August 1944; the Saint-Nazaire and Lorient areas surrendered on 10 and 11 May 1945. In 1941 the Vichy government removed Loire-Atlantique from the Brittany region.

In 1956 Brittany was reconstituted as a region without Nantes, and Loire-Atlantique went into Pays de la Loire with parts of Anjou, Maine and Poitou. Nantes, the prefecture, is considered by many to be Brittany's capital although the department sits outside the region.

The rings are approximate — deliberately. They exist to shade which filing system a place fell under, not to adjudicate a border. A place near a ring's edge should be checked against both neighbours.

The map takes a range, and a range that crosses one of the rows above is where records get lost: the family never moved, and the archive on the far side of the handover will tell you it holds nothing.
