Although marriage negotiations had languished since his accession, Louis did leave two illegitimate sons, Antonio (Anthony) and Luigi (Louis), who were sent to Barcelona to be raised by their aunt Eleanor, queen of Aragon. On 10 October 1355, days before his death, Eleanor had written to Louis to reopen the negotiations for his marriage to Constance, her stepdaughter. Negotiations were apparently also underway for the hand of a daughter of Matteo II Visconti, ruler of Milan, and for the hand of the King of Naples's niece Margaret of Durazzo, ten years Louis's junior.
