Hi maybe your Gaetano coming from Lercara Friddi (Palermo province). I cannot find a trip of Neustria ship by arrivals in new Orleans on 14 oct 1903; just the Massilia ship arrival..
and travelling some Lopresti coming from Lercara Friddi..
I found a Gaetano Lopresti born in Lercara Friddi on 23 Sep 1878 son of Antonino Lopresti 34 old and of Benedetta Nicosia.
