DNA tests have proven to be an invaluable tool for genealogists as they help connect long-lost family members. For instance, I was able to find out about Célestin Sauvage, a brother of my great grandfather, whom I had no information on before. Thanks to an Autosomal DNA match, I discovered that Célestin had left Crysler, Ontario and moved to Marshall, Minnesota in the late 1890s.

There is a Y-DNA test that could help us find the origins of Jans Sauvage. Y-DNA is inherited by men from their fathers and changes very slowly over generations. This means that men have the same or very similar Y-DNA as their fathers, grandfathers, great-grandfathers, and so on.

When I took a Y-DNA test, I am a descendant of Jans son, Benjamin, my Y-DNA matched that of a descendant of Benjamin's brother, Jean. By triangulating both Y-DNA, familytreedna.com was able to identify Jans Sauvage's DNA.

One day, a person named Savage or Sauvage from France may take a Y-DNA test. This could help us identify the region of Jans Sauvage's origins.
