John Wright IN Australia

I am looking for more info on John Wright born c1802, parents John Wright and Sarah Howe. John came to Australia around 1830? perhaps with one of the regiments, I have yet to find proof of this only a hunch. His occupation was noted as musician and most musicians at the time were with the regiments. He married Catherine Craddock at Parramatta 13 Feb 1842. Died 29th may 1862 in Sydney. Known Children John Thomas and Catherine Anne Any info on the Howe and Wright Families as well as John's wife Catherine Craddock would be greatly appreciated.
