I am looking at finding relatives who came on board SS Verona and SS America in late 1913 or early 1914 from Naples Italy

Assuming they came through Ellis Island, have you tried the Gold Form at: https://stevemorse.org/ellis2/ellisgold.html  If I search there for a: First Name starts with R, Last name starts with or is Leonardo, and Town Name starts with Rizziconi   Add ship to the results page... and search, I see one hit of Rosario Leonardo age 37 arriving 1906..... probably not yours??  

Hello, Thnk you for that link, search site. We know the SS Verona was the Ship, and it was 1913..We cant seem to get anything now prior to his arrival. 

If you "know" and the only way to be certain is to find the actual sheet on the manifest, that it's the Verona in 1913, and name indexes don't pick up your targets, then you could go through the manifest image by image.  Here's the 1913 voyages of the Verona coming into Ellis Island:  https://stevemorse.org/cgi-bin/boat.php?series=&rollStart=&rollEnd=&volumeStart=&volumeEnd=&monthStart=&dayStart=&yearStart=1913&monthEnd=&dayEnd=&yearEnd=1913&boatkind=starts&boat=Verona&offset=1&portkind=starts&port=&pageSize=50&database=all&local=yes&auth=  The name of the ship is the link to the manifest.

If for some reason the manifest is degraded and missing sheets,  then you could look at the "Book Index" for the Verona's voyages at: https://www.familysearch.org/search/catalog/452522?availability=Family%20History%20Library,  If you are not aware of this resource, see my essay at: https://www.jewishgen.org/infofiles/degradedmanifests.html  This is probably a faster way of finding a person on multiple journeys of a ship... it will show the sheet and line number of the person on the manifest.
