 Paolo was thus the progenitor of the Malatesta di Ghiaggiolo line which became extinct in 1757 with Lamberto.The union was not happy, however, as the young man's feelings were for his sister-in-law Francesca da Polenta, wife of his brother Giovanni, who had aroused keen interest in him since their first meeting when she thought she had to marry Paolo and not Gianciotto.In fact, at the proxy marriage, celebrated in Ravenna, Paolo represented Gianciotto.
