Chinese ancestor in New South Wales, Australia 1860's

[jenni]

I am trying to find a man called PiSchong who came to Australia about 1850 to work on the goldfields at Uralla, New South Wales. He obviously could speak English as he was called on to be a court interpreter at the Armidale NSW  Courthouse. From his death certificate I see he was born at Amoy about 1830 , died at Rocky River on 19 August 1865.  Pi Schong is the father of my great grandmother and I would very much like to know about his life.
