A French-language study examining how personal names preserve and express Breton identity. Drawing on the origins, forms, and historical development of names of people in Brittany, the book connects naming practices with regional culture, family memory, and linguistic heritage. It considers Breton and French influences, the survival of local forms, and the ways surnames and given names can illuminate settlement patterns, social history, and cultural continuity. Written for readers interested in Brittany, genealogy, Celtic studies, and French regional history, the work uses names as evidence for understanding how communities have defined themselves over time.
