Julia,
I found this posting on Rootschat. It mentions the Moran brothers.
Nelly brothers from perhaps Gort
Patrick Thomas Moran
Patrick Thomas Moran (abt.1811-1890) | WikiTree FREE Family Tree
On the convict listing for the Eliza, I found on Ancestry, it is noted for both brothers that they had a cousin, Peter Larkins, 12 years ago. I assume that is when he was jailed.
From the WikiTree site above
"On their shipping records state a cousin of theirs was transported 12 years earlier:
Peter Larkin - cousin of Michael and Patrick Moran. Peter Larkin born in 1787 in Gort and died in 1879 in Dapto NSW. Tried with Gleeson and Patrick Staunton in Galway Ireland in August 1820 convicted at the Galway Assizes for burglary and seditious practices. Patrick Staunton was not indicted on the capital charge. Peter Larkin and Gleeson were sentenced to death but Larkins was reduced to transportation for life. Peter Larkin and Patrick Staunton sailed from Cork on 16/06/1821 and arrived in NSW on 07/11/1821 on board the "John Barry" "
