This family is outlined in the book 8 Brown Threads by Alleyne Hockley.
I found these items recently which descendants may be interested in..
Adverts from The Argus 20 March 1852.
"If George Brown and George Bull, who arrived in Sydney, lately, from Slaughterford, Wiltshire, will call or send to Kinlochewe, Sydney Road, on Mr Thomas Barrett's farm, they will hear of Paul Brown who is living there."
The Sydney Morning Herald 26 July 1852 .. same repeated in July and August.
" If George Bull, who married Naomi Brown, and arrived in Sydney per Emperor , 6th June, 1851, also George Brown, who came to Sydney per Sarah, 14th August 1851, will communicate their whereabouts as early as possible to their parent, Paul Brown, care of Captain Pearson, Mount Ridley, Kinlochewe, Melbourne; or, to Mr John Clarke, Bankside Cottage, Balmain, Sydney, such communication with be thankfully received."
Bendigo Advertiser 6 March 1905. "A NEW FIND. Raywood, 4th March. It is reported that Messrs. Brown Bros., of Kamarooka or Neilborough North, have struck a payable reef at the back of their farm, on the edge of the Kamarooka Forest. A crushing of some 11 loads, it is stated, proved highly payable. The reef is about 2 and a half feet wide, and is located 40ft. from the surface, in a shaft sunk many years ago. It is supposed to be on the Wombat line, on which highly payable yields were got some vears ago. Several claims have been pegged out. The claim is on the Forest Reserve, and there is plenty of ground available."
It seems likely that the mine made a modest return as my great-grandfather Paul Brown jnr bought another farm of 409 acres just 3 years later on 1 March 1908 at an auction in Raywood, paying 9 pounds 7 shillings per acre.
Bendigo Advertiser 15 September 1922 " Neilborough North. A very pleasant gathering assembled at the residence of Mr Paul Brown at a party given by his family in honor of his 86th birthday.About 60 guests sat down to dinner, which was beautifully laid out in the new barn. The Rev Mr Graham presided. After the guests had done justice to the good things provided, the chairman called upon Mr Wm Ritchie to propose the health of Mr Brown. In doing so Mr Ritchie said that he was pleased to be present on this occasion as out of the many old pioneers of the district when he came amongst them he was sorry to say there were only three remaining. In proposing the health of Mr Brown, he said that he looked upon Mr Brown as a great man, a man with a warm heart, and a man loved and respected throughout the district. He wished Mr Brown many more years of health and hoped we would be spared to give us many more invitations. The toast was honored by singing "For He's A Jolly Good Fellow." Mr R J Frazer, in speaking to the toast, spoke very feelingly of the good qualities of Mr Brown, and said that he would be looking forward to the near future for another such gathering as Mr Richie had stated there were three of the old pioneers left. Mr Arthur Brown, in responding on behalf of his father, thanked Mr Ritchie and Mr Frazer for their very kind remarks and he appreciated the manner in which the health of his father had been honored. He was pleased to see all the friends assembled on this occasion and he hoped that his father would be spared to see many more birthdays. Mr Brown is a native of Slaughterford, England, and came to the country when in his youth. After dinner, singing recitations and games were indulged in, and a very happy afternoon was spent. Great praise is due to Mr Brown's family for the very fine spread given in honor of their Bonzer Daddy, as they called him."
