Aldfaer, a free genealogy program
Aldfaer is a free to use Dutch genealogy computer program which has
been in common use for many years by at present more than 10,000 genealogists and geneticists primarily in Holland and
neighbouring countries. Aldfaer run on Windows PC's and was the first genealogy program to implement
The Knot System relationship notation, which was released in Aldfaer version 3.02
by late 2004.
The program is under continous improvement by the development team with help from other contributors. The newest
iteration of the program Aldfaer version 8.1
was released in mid April 2020.
Unfortunately the homepage, documentation and specifications of Aldfaer only exist in Nederlands (the language of the Dutch people) and that makes it hard for the rest of us to benefit from the rich capabilities of this genealogy program.
Intensive use of Internet translation facilities like Microsoft Translator or translate.google.com may bring you a long way in trying to understand Aldfaer, how to install it and not the least to benefit from its implementation of The Knot System.
The purpose of this homepage is to help you download and install the program, make it communicate in English or other languages and import a GEDCOM file with your family data to be able to experience a practical implementation of The Knot System.
An Install Aldfaer Guide describing these installation processes in English can be downloaded here.
