His life is recorded in the Chronicle of Henry of Livonia; even though no other sources mention his name, he is considered to be one of the most influential pre-Mindaugas Lithuanian nobles.
This marriage protected Visvaldis from attacks of Lithuanians, but he had to provide food and shelter for the troops of Daugirutis on their expeditions to plunder the Estonian or Russian lands.
When his friends arrived to discuss the terms of release, but did not bring enough money for the ransom, Daugirutis killed himself.
If Daugirutis was weak or ruled only small territories there would be no point for Novgorod in negotiating with a petty noble.
The Lithuanian raids to Livonia and other lands decreased greatly in number after the deaths of Daugirutis and Steksys.
