His son, Ugo, together with his brothers Benedetto, Inghilberto and Urso, was granted the fief of La Fratta (the old name of today's town of Umbertide[1]) by the Emperor Otto III.

In 1612, Pope Paul V confirmed the privileges over the castle of Civitella and the title of counts to Costantino III, son of Ruggero IV and of Castora Della Staffa, and extended them to his descendants.

Costantino's wife, Porzia Varani of the Dukes of  Camerino, in agreement with her sister Olimpia,  gifted the castle of Beldiletto to the Ranieri family and gave birth to her husband's sons Tancredi and Ruggero (+1646), Knight of Malta.

He married Eleonora Degli Oddi, who inherited the feudal county of Laviano from her father Tiberio, which she passed on to her firstborn son Costantino IV (1624-1679).

Ruggero and his wife Marianna Gavotti Verospi had a son, Giovanni Antonio II (1822-1893), who organised a model farm on the lands of the former fiefdom with the help of the farmer Pio Gori.

He was a very skilled soldier, known for his contribution in the battle of Motta di Livenza (TV) and for being the ally of the great Italian military leader Braccio Fortebracci da Montone.

Known as "il viaggiatore" (the traveller),[6] he left an account of a journey he had undertaken in northern Italy with his son Curzio and the latter's newly-wed wife, Countess Flerida Olivieri.
