The Arezzo family settled in Sicily in the 12th century – around 1130 – in which period Aldo I, coming from Rome, appears at the service of King Roger. Later on this lead to the establishments of many family branches and lineages, initially in Siracusa, later in Ragusa then in Palermo, alongwith investitures of many noble titles in addition to being rewarded with manors (Cardinal 1392 Targia, S. Giuliano, Crocifia, Serri, Calamezzana, Donnafugata, Celano, Trifiletti, S.Filippo of Columns , Gaddimeli, etc.).
The Arezzo di Trifiletti, originating from Siracusa, are the main branch of the Arezzo della Targia; from the end of the 17th century they relocated from Noto to Ragusa resulting from a marrigage between Baron Don Domenico Arezzo Prado with Donna Concetta Sortino Casa.
In the middle of the 1800’s their son Carmelo purchased the noble residence destined to become the family palace in Ragusa Ibla, in which his descendants still reside to-date.
