Oltre al figlio nato dal suo matrimonio, C. lasciò ‒ come tanti altri suoi contemporanei ‒ un figlio naturale, anch'egli di nome Corradino, che tuttavia non svolse mai alcun ruolo di rilievo e fu giustiziato da Carlo d'Angiò nel 1269 dopo la capitolazione di Lucera.

(Google translates)

In addition to the son born of his marriage, C. left - like many other contemporaries - a natural son, also named Corradino, who nevertheless never played any important role and was executed by Charles of Anjou in 1269 after the capitulation of Lucera.
