He left S.A. in the 1850's on board a ship called the "William Hill" ? and headed for the Victorian goldfields. He was a police officer in Adelaide between 1848 - 1852. He left behind two sons, Henry Arnold jnr and Frederick. His wife's name was Elizabeth nee Parker who died in 1848 while giving birth to twin girls.
While in Vic. he remarried twice. 2nd marriage was to a Ellen Yuill,
3rd marriage was to a Sophia Bingley, I am looking for any decendants from these two marriages.
Note: there may be some errors in this info, there were a lot of Kempsons in Victoria in the 1800's
