I saw Catherina's manifest and she is from Rodi Garganico coming to see her husband Tommaso. Is this the only information you have that Tommaso is also from Rodi?
If your Tommaso had a brother, Donato...this might be his manifest.
First Name: Tommaso
Last Name: di Felice
Ethnicity: Italy, Italian South
Last Place of Residence: Narrea
Date of Arrival: Apr 26, 1905
Age at Arrival: 35y Gender: M Marital Status: M
Ship of Travel: Cretic
Port of Departure: Naples
Manifest Line Number: 0022
One last maybe here... The manifest says he is from Narrea, but I think it should be Barrea,
If you are not positive Tommaso is from Rodi, why not email to Barrea
and ask them to search there records for his birth act.
Here is a site to construct your letter
Hope some of this helps,
