Hi Andcarred,
I am a direct descendant of R J Inch of Blackheath. He is Richard Jeffree Inch. He was, as others have supposed, born in St Austel, Cornwell and married to Harriet Blackford. He came to Australia with his parents Charles Inch and Eliza Jeffree, as a young man. He had one sibling, a brother David Jeffree Inch. They came to Hill End and were gold miners along with a clan of Jeffrees. I have no knowledge of any other Inch family at that time. They went into Cordial manufacture and Brewing at Hill End. Richard Jeffree Inch moved to Hartley and then the Blue Mountains at Lithgow and Blackheath. At Lithgow he founded and operated Inch Brewery in Inch St, Lithgow. The building has since gone.
His brother David married Hanna Pattinson and had a son Richard Jeffree Inch, who went to the Boer War. On his return by troop ship he was badly sunburned and in delirium jumped over the side and was lost drowned. Coincidentally a chap contacted me about 4 years ago and informed that he had RJ Inch's (David's son) service medal that he bought at a flea market. It was traced by the number embedded in the edge.
Our subject RJ Inch also had a son Richard Jeffree Inch, who only recently passed away and with whom I had been in contact.
Our subject RJ Inch sold up in Australia, left his wife and family to follow him once he was established and began a coffee growing venture in partnership with another investor in present day Vanuatu. As the family were about travel by ship to reunite, they received word that he had died of Blackwater fever (malaria). His gravesite has never been located and the investment he took with him was never returned to the family. Hmmm???
All persons I have mentioned are accounted for as far as gravesites except for RJ Inch my GGGrandfather as already described.
I do not know who this Dr Inch is but I am mightily intrigued.
I hope this information may assist you and I hope to hear more if you find anything else.
Photographs of M Inch (actually RJ Inch, the M was part of Mr) and David Inch are to be found in the photograph section at NSW State Library online.
regards
Greg
