Maestro Vito marries Calogera Maida, daughter of Giuseppe Maida and Gaetana Palumbo, on 29 April 1823.
Vito and Calogera have at least four children: Francesco Paolo (c. 1820), Rosa (c. 1826), Biagia (c. 1829), and Vincenza (c. 1833).
In 1834, Maestro Vito Vasi, 35 (b. 1799), wife Calogera, 34 (b. 1800), and children Francesco, 14 (b. 1820), Rosa, 8 (b. 1826), Biagia, 5 (b. 1829), and Vincenza, 1 (b. 1833), live in the same courtyard in the San Nicolo' quarter as the families of Vito's brother, Maestro Pasquale and Calogera's brother, Calogero. Based on previous censuses, this is the cortile dell'Addolorata, named after the nearby church, where Vito's family lived in 1812.

Francesco Paolo marries Salvatrice Berlingeri on 12 June 1853.
