Thank you so much, Peter. This is a wonderful expansion of information to that which I already have.
Isaac Green of course was Frances' father.
I have not until now encountered a Paxton.
Am guessing that Abraham Green was one of the bride's brothers - but I am certain that Martha Green was her sister, as Martha married William Keeler Hawkes and they (Mr. & Mrs. Hawkes) some time after the Gaunts', also travelled here to Tasmania (previously Van Diemen's Land), to found a school.
Not sure where Elizabeth Hudson fits in the picture. Matthias had a sister, Elizabeth, but her daughter, Matthias' niece, was Hannah Jackson who eventually married Frances' brother Richard Green (the Gaunts', Hannah Jackson and Richard Green all travelled here together, arriving in 1831).
I have, since I joined this site, discovered that Matthias Gaunt came from Denby in Yorkshire, but it has been difficult putting a clear picture together, as I can't find very much on the Net about Denby, nor of the Anglican parish church there, the design of which influenced Matthias when he had a church constructed here similar to that in his home place. The little church here the good doctor named St Matthias.
I don't wish to appear to greedy in this search for information, but I can see from these responses I have that there's a very keen community of genealogists and researchers out in the wider world - and I do find these searches can become rather addictive!
Having qualified with the above statement, I go on to consider where Dr. Gaunt may have attained his medical training. Although we find he is practicing in London around the time of his wedding and later, do you think it possible he could have been trained in Scotland, considering he was from Denby, or is that just a wild supposition on my part?
Would the church have still been issuing surgeons' licences at that time - say around 1820 - or would the requirements have moved on to a university qualification by then?
Finally, in one reference I have to Dr Gaunt, he is noted as: Dr. Matthias Gaunt, MD RN - so was he at some time a ships' surgeon?
Questions, questions...
I'll simply throw the above into the mix and look forward to any responses that may come as a result... Cheers... Rose
