Given that there is some evidence to suggest Richard Gibson was in London c1812 ( is that correct? )
Wonder if he spent time in the debtor's prison, the pics below were taken from London's King's Bench and Fleet Prison Discharge Books and Prison Lists. There are three entries for a Richard Gibson, one dated 19 Mar 1804, another dated 22 Jul 1811 and lastly 'committed' 1 May 1812 discharged 10 Sep 1812.
I am aware there were a father and son, both by the same name in later registers and newspaper articles going bankrupt also at later dates
