How do I find who someone traveled with on a ship?

[Nazaro1970]

Hi all. What is the easiest way to find out who traveled with my great grandfather on the Iniziativa which arrived in New York 04/02/1891? His name was Pellegrino Nazzaro. Any help would be greatly appreciated.

Apparently Pellegrino from Atripalda was the only one with the surname Nazzaro travelling on that ship. Do you know the name of his wife?
