Ron , what is your connection to Thomas ? I am not related , but he was 50 when he arrived , had a sentence of 14 years ,when he was tried in Hertford, Hertfordshire, so it is most likely he did not have issue. There was another George Baker , who came on the "Hercules" in 1832 also went to Bathurst. Only marriage I can see on NSW BDM/Bathurst is in 1831 to Mary Fitzgerald at Kelso. There does not seem to be any children to this family. However if he married in 1831, you would expect him to require approval to marry , and there is none. There are records of his Ticket of Leave at the NSW Archives at Kingswood , can you go there ? From Trove a Thomas Baker was appointed a Constable in Bathurst 8/4/1837 , but was dismissed a month later.
