Trying to trace my 4 x G Greatfather Patrick Hargedan/Harrigan

Hi

I am trying to trace an ancestor who was tried and sentenced in December 1806 in Castlebar courthouse.

Depending on the documents I can find in Australia his name is either Patrick Harrigan or Patrick Hargedon or Patrick Hargedan or Patrick Haddigaddy  or Patrick Harrigham  he was born between 1780 and 1788.  I believe a relative probably his father or uncle was Edward Hargedan.  Patrick/Edward were from Foxford

He was sentenced to transportation for life to New South Wales Australia arriving in 1807 on the “Duke of Portland”

I am wondering if you know of any records still in existence  and is there any way I can have access to them.

Patrick was the son-in-law of James Ruse a First Fleeter and also credited with being the first farmer in NSW.

Any information or guidance in trying to trace Patrick would be appreciated

Thanks
