Duffy Family Around Kiltrustran

Hi All,

I am looking for relatives of Patrick Duffy (maybe James) my ggf, born 1821 in Roscommon died 1901 in Bellambi NSW Australia. He immigrated in 1876 with wife Catherine (Kelly) and 7 children Maria, Michael, Bridget, Catherine, Bernard, Anne, James. Five of the children were born in Ballygarden. Not sure but I maybe have a brother of Patrick whose name is Michael 1824 - 1881, also in Australia.

Also on Patricks immigration records it has him 10 years younger than the information on his death cert indicates and has his parents as Peter Duffy & Mary Dowd. Any help or info appreciated. details on ancestry family tree.
