Robert Caleb Jarvis (1816-1845)
Robert was baptised Robert Clary Jarvis in Woodchurch, Kent on 19 May 1816 the baseborn son of Frances Jarvis.  I have been unable to find anyone with either the first or surname Clary who could be the potential father and therefore presume this was a misspelling of Caleb, the name which was used in the future.
In December 1815 a few months before Robert was born, his mother Frances Jarvis was removed from Tenterden back to Woodchurch under a settlement order and is most probably the Fanny Jarvis baptised in Woodchurch in 1795.

In the 1841 census Robert and Rebecca with their baby daughter Elizabeth were living in Woodchurch listed under the surname Iden in the same household as Walter & Frances, two of their children and an illegitimate child of Julia.
Between 1841 and 1844 Robert and Rebecca had 3 children:
Elizabeth Rebecca b 1841
Eliza Feanills / Frances b 1843
Robert George Calip b 1844.
On 21 November 1844 Robert and his brother-in-law Hughes Mott were arrested for breaking into a house in Great Chart and stealing food and articles of clothing. According to the newspaper report they were both natives of Great Chart: Robert's wife Rebecca had been baptised there in 1822 and the Mott family certainly had a connection with the village.
They appear to have at first been in Rochester Gaol before being moved to Maidstone to await their trial.
At the Lent Assizes on 10 March 1845 Robert and Hughes were found guilty of the burglary: stealing two hams, two loaves of bread, three apple pies, a quantity of cakes, a gallon of mead and a velvet coat the property of Mary Beeching of Great Chart and sentenced to 10 years transportation.  A more detailed account of their trial can be found at the end of this blog.
Whilst awaiting transportation Robert appeared in court again: in April he was brought from Maidstone Gaol to Rochester Quarter Sessions to give evidence in an appeal about the settlement status of his family. 
General Extracts from the Journal of the Ship’s Surgeon of the Mayda 
The highlighting of words below is mine because although they are contained in the Surgeon's general comments, they relate to Robert, case no 30.
The convicts were embarked on the 19th of August apparently in good health and the ship sailed on the 27th. Whilst the ship remained at Woolwich some cases of sickness occured generally slight ones of diarrhoea obstipation and one of fever.
The convicts guards etc remained totally healthy during the month of September. Only four or five cases of fever occurring, with other slight cases the fever was generally of an inflammatory nature attended with considerable vascular excitement headache etc and was generally relieved by bleeding purging.
Early in the month of October, soon after we got the S E Trade Winds the convicts became very sickly a great number of fever cases occuring which were generally preceded by constipation . In most of the cases there was violent headache with pain [...] which in all was a prominent symptom.
Four cases terminated fatally two of whom were apparently getting well when the symptons took an unfavourable turn which soon carried them off, in one of them, no 30, there was great oppr[...] of breathing with apparent debility from the beginning and [...] did not relieve him to any extent, he was a man of a very broken constitution* and apparently had led a very irregular life.
[*Robert was 29 years old at the time]

In the 1851 census Rebecca was a widowed dressmaker living in St Margaret’s, Rochester with her two youngest children Eliza and George aged 7 and 6. The eldest daughter Elizabeth, 10, was living with her widowed grandmother Elizabeth Mott in Stroud, Kent. Rebecca appears to have remarried several times.
When Eliza married she gave her father’s name as Caleb and said he was a farmer.
Robert’s accomplice Hughes Mott died in Bendigo in 1857 in a fight with another miner.
