Peter Broun, son of Sir William and Annie married Caroline in 1824. He was one of the most important of the original settlers. As well as being Colonial Secretary until he died in 1846 he was Treasurer for the first three years or so and until the Legislative Council was formed he was responsible for organising nearly every activity, laws, records etc. He had very little assistance in the early years. It was an arduous task and probably contributed to his early death. Peter died on 5 November 1846 at Fremantle. He and his wife Caroline had thirteen children and many went on to be pioneers of our State. He is mentioned in many books on the Swan River Colony. Caroline departed the Colony per the 'Hindoo' 14 September 1848 for England and she died 22 March 1881 in Scotland.
