 In 1426 he married Costanza Trenta, who is at first sight not the wife in the portrait, as a letter by her mother of February 26, 1433 mentions that she had died.She was also from Lucca, and her aunt Ginevra Cavalcanti was married to Lorenzo de' Medici, brother of Cosimo de' Medici.On the other hand, Margaret Koster has recently proposed that the double portrait may be a memorial one, including an image of Costanza, but painted a year after her death.
