In 1826 the practice of John Ward Gleadow, one of the earliest private barristers and solicitors in Tasmania, was established and from 1827 - 1880 operated from premises in St John Street, Launceston. Gleadow later entered into partnership with William Henty until Henty's retirement in the 1840s. Gleadow's son Richard joined his father after Henty's retirement. In 1862 Richard Gleadow entered into partnership with William Ritchie and Robert John Parker. As 'Gleadow, Ritchie and Parker'. After R Gleadow's retirement, the firm carried on under the name 'Ritchie & Parker'. Sons of the original Ritchie and Parker kept the firm going until in 1912 Ritchie & Parker amalgamated with Alfred Green & Co, and continued in business as 'Ritchie & Parker Alfred Green & Co'. Alfred Green, who founded Alfred Green and Co. had served his articles under John Ward Gleadow. His son Alfred Lawrence Green took over from his father at Alfred Green & Co. The firm 'Ritchie & Parker Alfred Green & Co' operated at 81 St John Street until relocating to 10 Cameron Street in 1989. The Firm has historically been primarily involved in conveyancing and the management of family estates. As at 2023 the firm was still in operation.
