Louis married his second wife, Elizabeth, around 20 June 1353. Elizabeth was the daughter of Stephen II, Ban of Bosnia, and Stephen's wife, Elizabeth of Kuyavia. Louis and his new wife were within the prohibited degree of kinship, because Louis's mother and his wife's grandmother were cousins, but they applied for a papal dispensation only about four months after their marriage. Historian Iván Bertényi says that this haste suggests that Elizabeth, who had been living in the court of Louis's mother, was pregnant at the time of the marriage. If this theory is valid, Louis's and his wife's first child was stillborn. Their next child, Catherine, was born in 1370 and died in 1378. The next daughter, Mary, who would succeed Louis in Hungary, was born in 1371. Louis's youngest daughter, Jadwiga, who was born in 1373, became queen regnant of Poland.
