GeneaNet

Geneanet is an international genealogy database.

The story of GeneaNet begun in 1996 when several people interested in and computing, Jacques Le Marois, Jérome Abela et Julien Cassaigne, realized what a great instrument the  could be for their genealogical research.

They then had the idea to share, in a single database, not the whole of their family trees but what genealogists call a liste éclair (flash list). A liste éclair is a list of surnames which one studies is one's genealogy, associated to the locations where one's ancestors have lived. That file is often enriched with the years of the beginning and the end of which one holds information about each name.

Thus, comparing two listes éclair, it is very easy to determine if they have surnames in common and, if so, to check if these surnames are located in the same place. If, when, comparing two files, the chances of finding data in common are low, when hundreds, thousands, even hundreds of thousand files are compared, the probability of a hit are demultiplied! It is with this founding idea that GeneaNet was born, since the internet is a way to exchange and compare the listes éclair of genealogists worldwide.

Hence, a simple search in this « index of indices » is a way to know that a given surname, in a given location, between such and such year, is studied by a given genealogist (usually as a hobby).

The ancestor of GeneaNet was called LPF, Liste des patronymes de France. It was launched in June 1996.

The GeneaNet project was officially launched on 2nd December 1996.

Today the GeneaNet database holds over 135 million entries which is equivalent to over 400 million individuals.

One can also publish an online family tree very easily, by sending a gedcom file to the site.
