Girolamo Pietraperzia Barresi (c.1502 – 15 March 1549) was a Sicilian nobleman, marquis or prince of Pietraperzia, who was decapitated in Palermo after a prolonged process for the crime of murder and parricide.
His sentence for the murder of his father, Matteo Barresi, and two servants in 1533 was based on a confession obtained under torture.
His sentence was initially commuted by Holy Roman emperor Charles V, after extracting some hefty fines, but the new viceroy Juan de Vega ultimately enforced the death sentence.
[2] Girolamo had two children with Antonina, member of the Branciforte and Santapau families.
His daughter, Dorotea Barresi e Santapau, after widowing twice, including Giovanni III Ventimiglia, she married the new viceroy of Naples Juan de Zúñiga y Requesens.
