Giuseppe Monteleone, son of Antonino Montelone and the late Laura Lanza, from Chiusa Sclafani and a minor resident of Corleone, marries Giuseppa Sirina, daughter of Tommaso Sirina and Angela, from Palermo, on 22 November 1746 in Corleone.
Giuseppe and Giuseppa have at least two children, Leoluca (c. 1756) and Gaetano (c. 1760).
I estimate Leoluca is born by 1756, twenty years before he marries.
Gaetano is born around 1760, based on his reported age in the 1811 census.
Leoluca marries Maria Manicchia on 13 October 1776. Giuseppe has died by this time.
Gaetano marries Felicia Addamo on 24 September 1780. His parents have both died by this time.
