I am having difficulty finding the arrival record of my great grandfather in North America. I know that he lived in the province of Cosenza, Italy & departed Naples, Italy in the 1884 time frame identified as Napoleon Bellaspica Lepera. Are passenger departure lists available for Naples during this time frame?John - Ships Passenger lists for North America are best searched by arrival country or port, not departure port. The manifests were made at the port of departure, then turned in at the port of arrival.
You should be able to find your ancestor in ships lists on Ancestry.com. These manifests are indexed and linked to online images for both Canada and USA.
Be sure to use wildcards when searching as Lepera could be easily misspelled or badly transcribed. I would search using L*P*R* to pick up alternate spellings. Also, upper case "L" can be mistaken for upper case "S" by indexers so you may need to try a second search using S*P*R*
