I was able to find a Matteo Ciocca born in 1890 and a Felicia Ciccone born in 1895 that may match the people you are looking for. I cannot be 100% sure that these are your great grandparents though. My records do not go past 1899 into the 1900's when Pasquale would have been born. Would you be able to confirm a birthdate for either?
Luisa Vespoli will be a little harder to figure out without more information. Social Security might have her parents names, possibly burial records/death certificate from the state she lived in? There are also free data bases we could look at, but I would need to know where she lived.
I think your best bet to be 100% sure would be to write to the Town Hall of Macchiagodena and request a Stato di Famiglia for just the people you know for sure.
