Travel Document v Passport

[darkerhorse]

Two different persons named Nicolo Pitruzzello were naturalized in Connecticut, one in 1960 and the other in 1963.

I'm trying to determine when each arrived.

Two passengers named Nicolo Pitruzzello arrived in 1954 and 1958. Both have identifying numbers; the one arriving in 1958 is a passport number (6581988) and the one arriving in 1954 is a travel document (514073).

My theory is that the 1954 arrival was naturalized in 1960 and the 1958 arrival in 1963.

However, I was wondering what a travel document was as opposed to a passport, and whether the two arrivals could be the same person?

I really believe they are two different people, but don't understand why the different travel documents.
