He was born in Perth to carpenter William Kethel and Mary Watson. After a limited education, he was apprenticed to a shoemaker and then went to sea, travelling in the North Sea and the Mediterranean before arriving in Sydney. Here he worked as a timber merchant and eventually a ship owner. In 1861 he married Mary Ann Yeates; they had seven children. A Free Trader, he was elected to the New South Wales Legislative Assembly in 1885 for West Sydney. Re-elected in 1887, he did not re-contest in 1889.
