The Utica Daily Press, Thursday, May 26, 1960 edition on page... 26?... gives an obituary for him as he had just died the day before, that he was the son of Mr. and Mrs. Patsy Ferrusi, and that he was buried in Cedarville Cemetery. (Another source: "New York State Health Department, Genealogical Research Death Index, 1957-1963," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:2CHJ-HZ2 : 11 February 2018), Henry Ferrusi, 25 May 1960; citing Death, , file #34179, New York State Department of Health—Vital Records Section, Albany. ) The Herkimer NY Evening Telegram edition from Thursday, May 26, 1960 also gives an account of his death on page 5. It confirms his birth name is actually Enrico. His death certificate number is 34179, so you could actually order his death certificate from New York State, which should have more information on it. It's USD $22, at least, to order it though.
Based off of this site, it is most likely to find the Ferrusi family in the region of Abruzzo in Italy. The records for L'Aquila from Sezione di Avezzano and Sezione di Sulmona are not online yet, but if you ever go in person or hire a genealogist from Italy, you have the best chances of finding him there.
