David Shannon (c. 1822 – 9 September 1875) served one term as a member of the South Australian House of Assembly for the Electoral district of Light from 9 September 1858 to 18 March 1860.
They farmed together until around 1856, when David took up "Yatara", near Stockwell[5] (Stockport in some refs), where he died a few years after a fall from his horse and a subsequent infection which ended with a leg amputation.
David, his brother Abraham and four half-brothers migrated to South Australia around 1840–1850, though details are hard to find.
Many are interred in the Shannon mausoleum, Truro.
Half-brothers: No clear family link has been found to David Shannon (c. 1854–1900) who married Mary Ann Scott Murray (1859–1929) on 25 July 1877, home "Murray Flats"; or to David Shannon who married Deborah Kelley at Kapunda on 30 December 1865.
