Ancestry have this information under Passenger Lists in the Immigration Search function. Let me know if you can't access it.
I have never been able to tie 'my' Gallens to the Moys at Raymond Terrace (as you may have gathered from all the posts on the Gallen and Moy forums). I am still working on it though. I now have a records of William Gallen's marriage to Bridget Moy, and the subseqent birth of Patrick in Killygordon.
There are quite a few family trees on here..but a word of caution..not all the information is correct.
Let me know if I can help in anyway.
ps I was only looking at the Jetstar sale last night thinking hmm only $59 to Newcastle..I could just fly down and do some research over a weekend..had to slap myself around haha..
