Henry (Arricus or Arrico) (1160–1172) was the youngest and second surviving son of William I of Sicily by Margaret of Navarre.
Henry was present with William at Taranto, where the young king awaited his Greek bride.
According to legend, he was betrothed to a daughter of Malcolm IV of Scotland on his deathbed, but this is false.
He was originally buried in the chapel of Saint Mary Magdalene, but was moved by his brother to Monreale,[2] the final resting place of most of his family.
The death of Henry made his aunt Princess Constance, confined to Santissimo Salvatore, Palermo as a nun from childhood, the only legitimate heir to the throne; despite this, she remained confined in her monastery, until 1184.
