He married María of Navarra, daughter of Carlos II of Navarre, on January 20, 1393 in Tudela, Navarra.
After her death, he contracted a second marriage with Violant of Villafeliche. He had no legitimate children but a son out of wedlock named Jaime of Aragon, whom his father inherited with the barony of Arenós and other places. Alfonso the younger prompted the construction of important monuments such as the Monastery of Sant Jeroni de Cotalba and the Ducal Palace of Gandía, which were formerly initiated by his father Alfonso of Aragon and Foix, the old.
On his death without legitimate descendants came a lawsuit by the succession of their territories, which was resolved temporarily giving Gandia to Hugo Cardona and Ribagorza.
A few years later, in 1433, Hugo de Cardona Juan II of Aragon must cede the Duchy of Gandia the infant Juan of Aragon, future. In this way they returned to join the titles of Duke of Gandia and count of Ribagorza.
