The Dictionary of Australasian Biography/Thomas, William Kyffin
Thomas, William Kyffin, second son of Robert Thomas, was born in Fleet Street, London, in 1821, and emigrated to South Australia with his father in 1836, and from that time until the day of his death Mr. Thomas was intimately associated with the fortunes of the South Australian Register, for the last twenty-five years of his life as one of the proprietors. To his industry and ability in the different capacities in which he acted was due to a large extent the high character and phenomenal success of the Register, and the weekly and afternoon journals issued from the same office—the Adelaide Observer and Evening Journal. The firm which now conducts these papers bears the name of the subject of this notice, being known as W. K. Thomas & Co., and consists of of Mr. John Harvey Finlayson and Mr. Robert Kyffin Thomas, the latter being the elder son of Mr. William Kyffin Thomas, and grandson of the founder of the Register. Mr. Thomas died on July 4th, 1878.
