How can we measure the contribution of a volunteer to a field as vast as online genealogy? Jean-Louis Garret dedicated a significant part of his life to structuring, indexing, and sharing civil status data on collaborative platforms. His work, far from being a local anecdote, has fed databases used by thousands of amateur and professional researchers across France.
Structuring Old Records: The Garret Method on Geneanet
Most volunteer contributors in genealogy simply transcribe raw records. Jean-Louis Garret took a different approach: a systematic indexing of individuals and records with fine structuring (names, dates, places, type of record).

This rigor has allowed Geneanet to create what the platform describes as a “bulk record database created by Jean-Louis Garret” for various French localities. The term “bulk” is misleading: it refers to a collection covering several municipalities without a predefined geographical grouping, but each entry adheres to a format usable for historical or demographic research.
For those who wish to learn more about Jean-Louis Garret, his records testify to an approach that goes beyond simple amateur collection and resembles the work of a volunteer archivist.

Collaborative Genealogical Databases: What Garret Changed
Before the democratization of collaborative platforms, genealogical records remained scattered in personal notebooks or limited print association bulletins. Jean-Louis Garret understood early on that digital technology transformed the reach of each record.
A Large-Scale Contribution Model
His collections, integrated into Geneanet, are identified by name. Each researcher querying the database for a municipality covered by his records has direct access to his work. This traceability is uncommon for a volunteer contributor.
The RFGénéalogie website describes him as a pioneer of online genealogy, highlighting that he “tirelessly created databases, wrote tutorials, assisted in software design, and compiled various directories.” The diversity of his contributions goes beyond mere record collection.
| Type of Contribution | Description | Impact |
|---|---|---|
| Record Transcriptions | Structured indexing (names, dates, places) for several French municipalities | Direct reuse by researchers on Geneanet |
| Tutorials | Practical guides for using online tools | Training of beginner genealogists |
| Burial Indexing | Complete record of all cemeteries in Nantes | One of the largest burial collections on Geneanet |
| Software Design | Participation in the development of genealogical tools | Improvement of software used by the community |
The Case of Nantes Cemeteries
Among his most cited achievements, the complete indexing of the cemeteries in the city of Nantes serves as a reference collection. RFGénéalogie specifies that he was “one of the largest contributors” to the burial indexing project on Geneanet. This work now allows for the location of graves without physical travel, a considerable time saver for families and historians.
Sharing and Free Access: A Positioning That Shaped the Community
Jean-Louis Garret was described as an tireless advocate for sharing and free access. This positioning was not merely ideological: it had concrete consequences on how genealogical data circulates in France.
At a time when some associations charged for access to their records, Garret systematically made his collections available without financial compensation. This stance helped normalize free sharing on major collaborative platforms.
- His records are accessible without a premium subscription on Geneanet, making them available to the largest number of researchers.
- His tutorials enabled genealogists without technical training to contribute in turn to online databases.
- His indexing work served as a methodological model for other volunteers wishing to structure their own records.
References to his tools and publications were “very numerous” in the Internet and Genealogy guide until the 2018 edition, according to RFGénéalogie. This prolonged editorial presence reflects a lasting influence on industry practices.

Intergenerational Transmission: Records Still Used After 2019
Jean-Louis Garret passed away on May 29, 2019. His collections continue to be accessed on Geneanet, where they remain identified under his name. This longevity distinguishes structured digital work from mere handwritten collection: the data outlives its author and remains usable without further intervention.
For genealogists discovering his records today, the name Garret appears as a reliable source, associated with a rigorous method. The scientific reuse of his data (historical research, demographic studies) extends the utility of his work well beyond the family circle.
The journey of Jean-Louis Garret illustrates what a methodical contributor can bring to an entire field. His structured records, tutorials, and commitment to free access have shaped the practices of collaborative genealogy in France. The databases he created are still consulted daily, proving that the rigor of indexing outweighs the raw volume of data.
