Carlo I del Carretto
Carlo I del Carretto was a son of Giorgio del Carretto and founder of the Zuccarello branch of his house. Under the family settlement of 1385, after he ceded his share of Finale to his brother Lazzarino I in 1390, Carlo kept the Clavesana lands around Zuccarello.
A close ally of Gian Galeazzo Visconti, he was in 1397 invested as the first marquis of Zuccarello. By Pomellina Adorno he fathered Ilaria, who in 1403 married Paolo Guinigi of Lucca; her tomb there was carved by Jacopo della Quercia.
