If you can believe the two ship manifest, one with Domenico coming over in 1905 as a single man and then coming back in 1913 as a married man, you might be able to find his marriage record on film at a Family History Center.
The records only go to 1910.
If you don't find it there, you may have narrowed the date down to 1910-1913 in which case you can try emailing the comune and ask for their marriage record.

Here is the site I found the email
