 Alvydas Nikžentaitis suggests that he was Margiris because sources attest to his high status and wealth.Sources mention one son of Margiris, who was captured by the Teutonic Knights soon after his father's suicide in 1336 and did not return.The only direct written mention of Gediminas' sister is a legend describing the murder of two Franciscan friars who came to Vilnius to spread Christianity.
