I would be interested in seeing your info, I google earthed Garryduff and it is a strong possibility that we have the same/related Catherine. My searches have led me to Swiftsheath(definate), New Ross, Ballyraggett,Wexford areas. I know for sure Pat&Bridget, Michael &Bridget(Brenan), Mary and another sibling, father Martin& Anastasia (Griffen) and the Farrells were living in Swiftsheath from their .,immigration and Land applottment details, although they were not born there but New Ross/Old Ross etc. They were RC and the Lannan name appears in that section of many of the graveyards. So we are both in the same area!
From some of the titbits I have read about Patrick in Australia, I get the impression that they did not leave Ireland only because of the potato famine/better opportunity but Pat was probably IRA leaning and a bit of a lad! Brother Michael went to USA and another brother/cousin Edward may have gone to Canada but not sure about him yet. Mary Lannan (sister) married Edward Kealy and came to Australia.
I have sites on both Ancestry.com and My Heritage.com, if you would like invites please send your email.
