Some of the history of the family in early times was researched by Filippo Bonugli (now deceased), a professor of history in Genoa, and below is a copy of an original document in which he tries to summarise some of his information.
"Since the year 1300 we find that the Bonugli were patricians of Forli. In 1525 Andrew of John obtained the title of noble and was one of the Ambassadors sent from the Senate to the Pontiff Clemente VII to obtain the approval of the College of Doctors. This family has given to her country Captains in the Army, doctors in laws, judges and exquisite Lord Mayors. She gave to the church famous prelates that with clear mind and military valour have been able to obtain her country a very good period of five years. At the beginning of the eighteenth century we find a branch of this house in Viterbo. From this family too, we find famous men that dedicated themselves to the Army, Sciences and Politics. This family is prosperous even now and still gains many merits.
Arms: Gold to the azure roe-buck surmounted by three stars".
