John Williams (1824 – 4 April 1890) was a pastoralist and politician in the colony of South Australia.
Williams was a son of Thomas Williams (c. 1794–1881) and his second wife Catherine, née Codd, who with much of their family emigrated on the Platina, arriving in South Australia in February 1839, and established a farm "The Hermitage" on the Little Para River.
[1] He purchased property at Black Rock in 1851,[2] which he developed as a sheep run, and with his brother George Sibley Williams (1825 – 20 December 1902) owned a sheep run at Parnaroo, east of Peterborough, with little success, largely due to the rabbit plague.
He died at his home "Halberstadt", Jeffcott Street, North Adelaide, after a long illness.
He married again, to the widow Maria Guy (née MacDowell) on 18 June 1872;[7] they had a home "Syward Lodge", Mitcham.
