Middlesex County voters elected this Gawin Corbin as one of their representatives in the House of Burgesses in 1764, to replace Ralph Wormeley, whom lawyers ruled had a British commission as customs collector, although Wormeley argued that the intended collector was his son Ralph Wormeley V. Corbin won re-election several times, and served through June 1770, although alongside several other men in the other part-time position representing the county in Williamsburg.Leonard, The Virginia General Assembly 1619-1978 (Richmond, Virginia State Library 1978) pp. 92, 95, 98, 100
