Modern Software Experience



GENDEX is an abbreviation of Genealogical Index. It the name of both a file format and a now defunct web site.

The original GENDEX was developed by Eugene W. Starks. He started the site in March of 1996. The site was a collective index for genealogies found elsewhere on the web. It contained names, dates and places but no relationships, for that you had to visit the original site it linked back to.

Starks developed a simple file format for submissions. That GENDEX format was first supported by his own GED2HTML tool, and soon by many more genealogical web site generations tools.


The service was terminated on 2004 Apr 22. On 2004 March 5, the following message appeared on the home page:

NOTICE: After operating for eight years (since March, 1996) GENDEX will be terminating its genealogy operations on April 22, 2004. All genealogy data will be removed from the system at that time. The GED2HTML program will still be available for download from another site, accessible via the link below. Thanks for your support for the past eight years! -- Gene Stark

At the time, it indexed more than 22.000 databases containing more than 60 million individual records.

Current GENDEX Sites

GenealogyToday Online Family Trees

GenealogyToday has a GENDEX service called Online Family Trees. It is presented as a single page on which you can search their collection or follow a link to submit a GENDEX file.

The site does not show statistics. It does not appear to be very popular. Names I regular search for did not produce a single hit, and a search for the surname Jones resulted in a list of just sixteen records.

Online Family Trees is a bare-bones GENDEX site.

TNG Network

The TNG Network was started on 2006 Jan 16, just after the release TNG version 5.1.1 and won Best New Product 2006.


The TNG Network was created to support TNG sites. It does not stop you from submitting GENDEX files for other sites, but it does assume that the GENDEX you submit is for a site with URLs that end with a personID like TNG pages do.
TNG makes it easy for its users to submit their site to the TNG Network.


The TNG Network home page shows the statistics. When I just visited, the it showed currently indexes 1.055 databases containing 7.065.060 names. That works out to an average of more than 6.696 names per database.


The TNG Network has support for the Firefox search bar, but you have to install it manually and it is for Firefox 1.0.


StamboomZoeker is a Dutch gendex site by Gerrit Veldman, started on 2006 Sep 25. The initial version was aimed at both TNG and PhpGedView sites, and specifically at Dutch family trees.


FamilyTreeSeeker is the English variant of StamboomZoeker. FamilyTreeSeeker was announced on 2006 Dec 23. It is just another name for the same site, but with an English user interface. There is just one GENDEX database.


When it started, FamilyTreeSeeker supported GENDEX files created by GedBrowser, GedPage, Ged2HTML, Ged2WWW, Ged4Web and Legacy Family Tree. Not long after its announcement, HuMo-Gen PHP added GENDEX output in support of StamboomZoeker. Today, FamilyTreeSeeker supports an fairly impressive lists of programs:



When FamilyTreeSeeker started, it already contained 2,7 million names from Dutch family trees. When I just checked it contained 13.436.816 names in 3.896 trees. That is an average of more than 3.448 names per tree.


One thing that makes StamboomZoeker / FamilyTreeSeeker especially useful is that it has a notification service not unlike GeneaNet. You can enter a name, and even a date range and place, to receive email notifications about new and updated sites.

I have been a subscriber since the service was started, and I have never received anything information about new matches. Those notifications are sent once a week, and only if there is a new match.

FamilyTreeSeeker is an add-supported site. All its functions are free to use, and there is a promise on the site that it will remain free.

I’ve saved the best feature for last. Not only does FamilyTreeSeeker provide support for the Firefox Search bar, installing it is just a matter of clicking yes.

2011-04-22: Retrospect-GDS, GED2WWW

The Infused Solutions site no longer has any pages for Retrospect-GDS. Retrospect-GDS is still an open source project on SourceForge. The link has been updated accordingly.

GED2WWW seems to be no more. Leslie Howard's entire domain is gone. The broken link has been removed.
