Hi Tom
I can let you have what I know of the Bacon's and Pawle's. Unfortunately I cannot trace Dr Pawle further back - he didn't leave any indication of his parentage on his death record and try as I might I have not been able to find birth records for any Pawle's in that timeframe.
I am descended from his eldest daughter Jemima who marraied William Charles Guest.
Dr Pawle came over on the 1820 settler migration as part of Wilson's Party. His letters of application and the references to Jemima's family are on
http://www.eggsa.org/ look under 1820 Settler correspondence. It would appear that his one son Henry Rigg Pawle died just beofore they left England in 1820 - there is a death record in the London Parish records. Jemima Pawle, according to her death record, was born at sea on the journey to South Africa though there is no record of that.
Also on the EGGSA site I have posted pictures of the graveyard where Dr Pawle is burried his stone is included - look under St Marks in George.
One of our relatives has tried to infer that Jemima Bacon was descended from Sir Francis Bacon - this is unlikely given he had no known heirs. They have also tried to infer that she was estranged from her family at the time of her marriage, again unlikely given a Stephen Bacon was witness to the Marriage.
I have copies of the parish records - including osome related to the van der Hoven connection so if you Personal Mail me your Email address I am happy to give you copies
Regards
Gillian
