Daujotas was one of the 5 elder Lithuanian dukes mentioned in the peace treaty with Halych-Volhynia in 1219.[1] In the same document Vilikaila is mentioned as brother of Daujotas which suggests that Daujotas was the older or perhaps more influential brother.[1] The brothers are not mentioned in any other sources.[1] Tomas Baranauskas, a modern Lithuanian historian, believes that Vilikaila and Daujotas might be sons of Stekšys, a Lithuanian duke killed in 1214.[2]
