Hi Pauline,
I had a quick look on Ellis Island site but couldn't see him. There were a couple of Gaughans from Attymass/Ballina.
Tom presumably emigrated from Gateshead but lots of people from Ballina went to Scranton area in Pennsylvania.
The later Ellis Island entries can be very helpful as they often give the person that the emigrant is going to (most likely a relative) and the next of kin back at home.
