Charles I Robert dated 24 February 1317, in which Maria is still mentioned as a living person. The resulting differences about the date in documents in charters could be explained as a mistake of the writer, who didn't place correctly the last number – rather than MCCCXVII he wrote MCCCXV and MCCCXVI. The picture of her funeral placed at the head of this article was a miniature of the Chronicon Pictum, who was currently preserved in the National Library in Budapest. After the death of Maria, Charles I Robert married Beatrice of Luxembourg in 1318, who died the following year in childbirth, and married lastly Elizabeth of Kujavia in 1320, who finally bore him the needed male-heirs of the dynasty. Issue The union between Maria and Charles I Robert was childless, probably because of the Queen's infertility. Older literature attributed to this union two daughters: Catherine (d. 1355), married in 1338 to Duke Henry II of Świdnica; their only child, Anne of Świdnica, was later Holy Roman Empress by her marriage with Charles IV of Luxembourg. Elisabeth (d. by 19 August 1367), married a "Bolesław of Opole" (probably Duke Bolesław II of Niemodlin). The existence of this two daughters as offspring of Maria of Bytom, supported by a group of Polish and foreign historians, headed by the genealogist Włodzimierz Dworzaczek, was recently challenged and rejected by historians. During Maria's lifetime, her husband had an illegitimate son, Coloman, born by the end of 1317 or early in 1318. The mother was a certain Guze (or Elisabeth) Csák, a daughter of George Csák. This son followed a Church career, and was in Bishop of Győr from 1337 to 1375.
