There really is no information about Francesco Mancuso other than that the information received in Spezzano was from the register of the town of Rossano (that should be in Cosenza), and that the record was dated there on Feb 28, 1869, no. 91, at 8 a.m. That's when the declarant(s) appeared at the town hall of Rossano to report Francesco's death. The specifics of his death such as his age, the exact day and time of his death, his marital status, possibly his parents' names, would be in another part of the record which you don't have. So I can't even say that he died on the 28th.
There are some online records for Rossano but, as luck would have it, the 1869 death records are missing.

Possibly there is someone at your local family history center who is also researching Italian records who could, at least, help you get complete copies of the individual records you need. You might also considering getting yourself a copy of the book Italian Genealogical Records by Trafford Cole. It would help you to better understand the formats of the records you are trying to locate and research. Good luck tomorrow.
