The written sources contain little information on Morta's family and it is not entirely clear how many children she had. Two sons, Replys and Gerstukas, are mentioned once in an act dated August 7, 1261. The act, by which Mindaugas granted all of Selonia to the Livonian Order, could be a medieval forgery by the Order. According to the Hypatian Codex, two sons, Rūklys and Rupeikis, were assassinated together with Mindaugas in 1263. This is the only information available and historians disagree on whether these were the same two sons, whose names were distorted by medieval scribes, or whether there were four sons.
