Ma Tribu is a family genealogy and history website created by Catherine Cadel Chauvigné-Bourlaud to bring together research, records, and stories about her extended family. Conceived as a meeting place and archive, it combines an online family tree with a broader collection of documents, biographies, historical accounts, and research resources. The genealogy database contains information on 9,822 people; access to details about people who are living or lived in the 21st century is restricted to registered family members. Registration is managed by the site’s creator and is intended for relatives.

The site traces family branches from regions including Brittany, Normandy, Poitou, Guyenne, and Picardy, and follows relatives whose lives reached Canada, Algeria, Africa, Japan, Tahiti, and Russia. Visitors can explore family names, biographies, timelines, archival material, and themed pages on migration and regional history. A forum supports genealogical questions and exchanges among researchers. Built using the TNG genealogy platform and the adHoc content management system, Ma Tribu presents genealogy not only as documenting facts, but also as preserving and sharing family stories across generations.
