St. Hubertus was the patron of the Ardennes forests. It was here that Dagobert II (the Merovingian King of Austrasia who lived contemporary with St. Hubertus and who was also made into a saint) was assassinated while with a hunting party on December 23, 679.
According to The Legends of the Jews by Louis Ginzberg, Cain also died while hunting, accidentally killed by his descendant, Lamech.
Just some interesting details. I may add more to this in the coming hours or days.
