Hi shume
As far as I am aware there wasn't a convict ship called the Kintchin. I believe that is a mistranscription of Florentia. I understand the 1841 ticket is a re-issue of the original 1834 ticket.
William Andrews alias Everett is convicted in 1829 and arrives in 1830. After he becomes free he uses the name Luke Everett / Everitt and is a builder in Albury.
James Heffering is convicted in 1827 and arrives in 1828. There seems to be no record of him after 1841.
It is James Heffering who may or not be J C Everett the blacksmith named in histories of Albury. I hope that clears up your confusion.
May I mention that James HEFFERING it is not usual for a second CF to be issued ... James must have needed a replacement document for his CF issued in 1834, so the 1841 CF document would be sufficient for him to leave the Colony of NSW and go 'anywhere', afterall, he had completed his servitude. Why would he have needed a new CF ... afterall he had been emancipated for quite a number of years .... Umm.... IF he wanted to leave the colony he would have needed proof of his status, and the CF provided that proof. He cannot find it ... so he decided to get it replaced. He would like go to the Police Magistrate ... there he would learn that he would have needed to apply for a new CF, and he would have needed to pay the fee too.
Turn back the clocks ... its 1841 - and you yearn to travel ... there's an economic downturn in NSW, so there's New Zealand, Tasmania, South Australia, China, California, England, Chile, Cape Town, The Straits, ... many ports - he just needed the funds to pay his fare, and the CF to prove he was Free to leave NSW. That's not to say he would have quit NSW, yes he may well have become known by another name, and have become a blacksmith in Albury, BUT .... both are simply speculations at this stage. Heffering is an unusual spelling, and I can only find one other by that surname on any NSW convict list (Patrick, per the Backwell in 1833).
