According to Gregory of Tours, he supplied refuge to Childeric I, the Frankish king who was exiled by his own people. After eight years, Childeric returned to Tournai. Bisinus's wife, Basina, left him and joined Childeric.
The historical Bisinus bears some resemblance to the Bisinus described by Gregory of Tours, but the details are different: Bisinus was the leader of a Thuringian confederation on the Rhine and his wife was a Lombard named Menia. He left three sons, Baderic, Herminafred, and Berthachar, who inherited the throne from him. His daughter Radegund married the Lombard king Wacho.
