What is PRDH-IGD? is a database of all Catholic baptisms, marriages and burials recorded in Quebec between 1621 and 1861 (nearly 3.2 million records) as well as a genealogical dictionary of families commonly known as “Family reconstructions”.

All individuals mentioned in these records receive their own “individual file” which centralizes the information available on the individual, along with links to the records in which they are mentioned.

In addition, every married couple receives their own “family file”, which fulfills a similar role as the individual file, but for a family unit.
It contains a list of the couple’s children with links to their respective individual files and vital events, as well as additional information about the married couple.

As a result, PRDH-IGD can be described as a detailed family tree of the entire French-Canadian population from the colony’s beginnings to 1861.

PRDH-IGD is the result of a rigorous academic effort spanning decades and is recognized worldwide as one of the most detailed and reliable demographic databases.
