The Sir Thomas Mitchell Inn was named for Surveyor-General Sir Thomas Mitchell

Alexander Munro held the license for the Sir Thomas Mitchell Inn until 1847 when he moved to the Governor Burke Inn

George Ledingham had took over the license of the Sir Thomas Mitchell inn in 1847. A Dinner was held in the room at the rear of Ledingham's 'Surveyor General Inn' in honour of Sir Charles Fitzroy on his visit to the district in 1847. The room was very neatly fitted up for the occasion with festoons and devices in flowers and evergreens. The dinner had been provided by Mr. Munro of the Governor Bourke Hotel and was 'got up in very good style; the wines were of excellent quality and in fact the whole affair seemed to give the greatest satisfaction'.31

George Ledingham's wife died aged 25 in March 1849 at 'Sir Thomas Mitchell Inn' 32

In December 1849, Alexander Munro transferred the license from the Fitzroy Hotel to the Caledonian Hotel lately known as the Sir Thomas Mitchell Inn kept by George Ledingham

William Winch was landlord of the Caledonian Hotel in 1862.

George Ledingham later held the license for the Sir Thomas Mitchell Inn located at the Namoi River
