I never heard of the surnames Nespoli, Farina and Caruso in Valle dell'Angelo but Nigro (originally from Piaggine) can be found there.
I have access to birth, mariage and death records of Valle dell'Angelo from 1809 to 1940 and can do some look ups for you to see if your Coccaro family is from Valle dell'Angelo if you have some dates.
