Welcome to Rootschat!
Cutting to the chase; if I understand you correctly, you’re looking for:
1. the baptism of Richard Clarke, born c1832, who emigrated to Australia in 1856, and whose parents he gave as John and Eliza née Hancock, and their marriage
2. Eliza’s death prior to 1856
If Richard said he was “born Cambridge” then I would be starting there rather than Cambridgeshire.
A good place to start is the Cambs FHS website at
http://www.cfhs.org.uk/Search.htmlBut the baptism index throws up no Richard Clarkes that fit. Or Richard Hancocks.
Nor can I find a marriage between John Clarke and Eliza Hancock.
If you do a parents search on the IGI – just complete James Clark and Eliza – there are a number of births/baptisms in Cambridge:
27 Apr 1821 birth, bap 19 Nov 1848, Gray Clark son of John & Elizabeth @ St Paul (he was born Somersham Hunts per censuses)
14 Feb 1826, buried 19 Feb 1826 John Clark son of John & Elizabeth @ Holy Trinity (Burial Index shows him as 5 days old, of King St)
Jan 1830 birth, buried 9 Feb 1830, Elizabeth Clark dau of John & Elizabeth @Holy Trinity (Burial Index shows her as age 11 of King St. Birth is invented!)
*17 Dec 1831 birth Alice Clark dau of John & Elizabeth @ St Giles
*10 Aug 1834 bap Mary Ann Clark dau of John & Elizabeth @Holy Trinity (Baptism Index – age 6 mths, abode King St, parents John & Eliza)
13 Dec 1838 bap James Clark son of John & Eliza @ St Peters
All bar Giles are member submissions which are unreliable, but with complete dates they look reasonably authentic. But only those marked * are on the Baptism Index on the Cambs FHS site.
There is another:
*10 July 1831 baptism John Clark son of John & Elizabeth @ Holy Trinity (age 24 of Somersham Hunts per Baptism Index. Ignore him!)
In 1841 at St Giles Cambridge
John Clark 35 Journeyman baker
Eliza Clark 25
Alice Clark 9
Mary Ann Clark 7
John Clark 5
James Clark 2
Charles Clark 1
All born in Cambs except John senior
By 1851 John was apparently dead and Eliza, widow, gave her age as 38 b Horningsea Cambs with children Alice 19, Mary Ann 17, James 12, Charles 9, Caroline 7, Alfred 2, Elizabeth 3mths.
Just about room for a Richard to have squeezed in, but why wasn't he baptised if the others all were? I think these may be a red herring.
Odd, I can’t see a death of John 1848-51, but there are three in Cambridge 1846-7. Had he perhaps done a runner.
Are you sure that Richard was the only Clarke to have emigrated? ie did he have any siblings in Oz?
"... death certificates do not help with UK information" - Just found your 2003 post where you gave the additional information that his father was a labourer and Richard was born in Kent per his death cert. Which surely is a help?
His occupation seems to rule out the John and Eliza family in Cambridge, whose marriage I can't find. You need a look up in Boyds marriage index to find if there's a marriage of John Clark(e) and Eliza Han(d)cock
The Camdex site at
http://www2.cambridgeshire.gov.uk/db/riddeaths.nsf/search?OpenForm sometimes gives ages at death which are not shown on the GRO index
