He was a son of "Micer" Filippo Pallastrelli (called Filipe Perestrello in Portugal), a Lombard knight who came to Portugal some say erroneously in the train of Queen Leonor of Aragon and here he was a Nobleman of John I of Portugal, who recognized his Coat of Arms and made him a Nobleman of Coat of Arms in 1433; he was married to Caterina Visconti (of the Visconti of Verona not from the ones of Milan), with whom he came to Portugal in 1385, and granted, in 1437, two houses at the Sub-Ripas Street in the City of Coimbra. He was the son of "Micer" Gabriele Pallastrelli, a Lombard nobleman from Piacenza, and second wife Bertolina Bracciforti.
