Anyway, 58 Cavendish, Stanmore, is reputedly his birthplace. Which is pretty close to where I grew up in Marrickville. The parallels end there, I suspect.
And yes, Holt St intersects with Cavendish. There's a clue there, surely.
So Smith the elder was alive and living in Penrith at the right time, but he had seemingly retired from politics after that 1906 defeat. He had indeed been the local member (the MHR for Macquarie) up to 1906 but not after that date. So technically he was the former member, not "the local member" as umpteen websites suggest. Could it have been his cricket-playing son, instead?"Defeated in 1906, Smith retired to his inherited estate, Thornton Hall, at Penrith. During World War I he lived in Sydney. His youngest son was killed at Gallipoli: Smith was president of the Sailors' and Soldiers' Fathers' Association (1923-28). A teetotaller and non-smoker, he was genial, earnest and energetic, with 'good judgement and a tenacious memory'. Smith died at Croydon on 21 February 1934 and was buried in the Anglican section of Rookwood cemetery..." (Australian Dictionary of Biography.)
"His eldest son Sydney was born on 1 March 1880 at Surry Hills and was educated at Annandale and Bathurst Public schools and at Hawkesbury Agricultural College. He worked as a bookkeeper on J. S. Horsfall's Widgiewa station in the Riverina and after being rejected as medically unfit for service in the South African War, joined the New South Wales public service in February 1902. In June 1912 he was promoted clerk in the stock and brands branch of the Department of Agriculture at a salary of £300 and on 30 December next year at St Philip's, Church Hill, married Minnie Violet Crossman (d.1969), a nurse. Chief clerk from 1919, he was secretary of the stock and brands branch, registrar of brands and of the board of veterinary surgeons in 1921-34, then chairman of the Local Land Boards under the Western Lands Act of 1901. He retired in 1944." (Australian Dictionary of Biography.)Nope. Apparently not. He was big in the world of cricket administration though. Folow that biography link for more on that.
