Saint Gabinus (296)

He was the brother of Saint Caius, the twenty-ninth Pope. He was the father of the beautiful little virgin martyr, Saint Susanna, whose feast is August 11, and who was martyred for her Faith and her purity, because she would not marry the son-in-law of the pagan Emperor Diocletian. Saint Susanna was martyred in 295, and one year later, in 296, her father, Saint Gabinus, shed his blood for the Faith for which his daughter had died.
