There are several webpages that mention Christopher Augustus Fearon and Grace Adriana du Moulin. This page looks at Christopher. The information below is an answer to a query posted in 2001 on genealogy.com and answered by by a great-great-grandson, whose name we haven't been able to glean. We quote his reply with slight modifications to formatting and (after checking N. S. W. Births, Deaths & Marriages) corrections to dates:

I suspect the Christopher Fearon you are looking for is my gggrandfather Christopher Augustus Fearon [CAF] b. Portsmouth 1788, died Sydney NSW 1866 at his property “Kishnagur”, which was situated about where Eastwood is now. CAF was married twice and fathered five children with his first wife Elizabeth (Noad, b. London 22 Oct 1794) and another nine with his second wife Grace Adriana (du Moulin, b. 1822). CAF was a trader/factor in China before and at the time of the Opium Wars. There is/was a Fearon Street in Shanghai named after him. CAF was appointed Vice Consul at Canton on 28 November 1825 (I have the original Warrant, signed and sealed by George IV). On 15 June 1843, CAF was appointed Consul after the death of the Consul (and business partner James Ilbury – firm name was Ilbury, Fearon & Co.). The Consulate was transferred to Hong Kong on 24 April 1844 (I have the original Patent of Commission). CAF’s first wife Elizabeth died at Lintin Island on 31 March 1838. As no foreign women were permitted at Canton (business only) all families lived at Lintin. When the trading port was moved to Hong Kong after the Opium Wars, Elizabeth’s remains were re-buried at the old protestant cemetery at Macau. CAF was 59 when he married Grace (22yrs), the last of the nine children he fathered with Grace was born when he was 76 years old.

I can give you full details of the main and cadet lines of the family from CAF. I have some (more fuzzy) details back from CAF.
