Ruth - for the moment it is only the photo of Matthew Trewhella that I need to comment on. I am certainly interested in details of your family back to Martha Jane but I will need to check back through my files to see what I have before discussing that line.
Two points to begin with:-
1. This photo is NOT of your Matthew
2. Even if it were your Matthew the dates are incorrect
1. This photo is that of the younger brother of my 2xgt-grandfather Benjamin. Matthew was born at Lelant 13th June 1841 and baptized there on 25th July. He travelled to Victoria with his brother John and arrived here in May 1855. The previous year my 2xgt-grandfather Benjamin arrived along with brother Christopher and all four brothers eventually ended up at Barry's Reef where they were successful miners.
Matthew Trewhella married Ann Dolphin at Blackwood in 1864 and died at Newbury (near Trentham) in 1935 at the age of 91. That photo is of Matthew sitting on the porch of his home at Newbury and I think it may have been taken by my great-grandfather William Trewhella.
2. Your Matthew was born at Phillack in 1852 and died at Bendigo 29th December 1922. He married Annie Hocking Thomas at Long Gully in 1882 and had a total of eleven children. I have copies of both his Marriage and Death Certificates although the informant at his death incorrectly named Matthew's parents as Matthew Trewhella and Margaret Jane. Matthew himself stated on his marriage certificate that he was the son of John Trewhella and Jane Chinn.
There was another sister who came to Australia as well - Catherine (born at Phillack in 1855) married James Stephens at St John's Church, Latrobe Street, Melbourne on October 3rd, 1889 and also nominated her parents as John Trewhella and Jane Chinn.
To my knowledge neither Matthew nor Jane ever went to New Zealand.
There was also one older brother. John Trewhella was born at Phillack in 1850 and married Jane Pascoe, widow (nee Bowden) in 1872. There were no children from the marriage and John died at Phillack in 1900 whilst Jane, 11 ears older than John, died at Phillack in 1905.
I suspect that between us there will be quite a few gaps to be filled so I look forward to our further discussions.
