From her first marriage, she was the mother of two daughters — Brunhilda and Galswintha — who were married to two Merovingian brother-kings: Sigebert I of Austrasia and Chilperic, king of the Neustrian Franks.
Shortly thereafter Liuvigild became king of the Visigoths, and Goiswintha became Queen consort once more, and stepmother to her husband's sons Hermenegild and Reccared I.
According to Gregory of Tours: "the Queen lost her temper completely" and "seized the girl by her hair and threw her to the ground: then she kicked her until she was covered with blood, had her stripped naked and ordered her to be thrown into the baptismal pool".
[2] Whether because of this fracas, or, more likely, because of Leovigild's desire to assure the succession of his sons (consistent with his previous actions to associate his sons with himself as rulers of the kingdom[3]), he sent Hermenegild and Ingund to Seville to rule a portion of his kingdom - presumably the province of Baetica and southern Lusitania.
There, Hermenegild was influenced by his wife and Leander of Seville to convert to Chalcedonian Christianity, and to rebel against the king.
