Location of Mill
Several sources give the address as Gaythorn Mill. The 1849 O.S. map  shows 'Gaythorn Mill' on the western side of Albion Street, by Medlock Bridge. However, there is a group of buildings on the opposite side of Albion Street, immediately north east of Gaythorn Mill, and this group, marked as 'Medlock Bridge Mill' and 'Gaythorn Small Ware Manufactory', accords with the description given in the 1841 advertisement above. The little River Tib defined the eastern boundary, and then entered the Medlock, and this was perhaps the only time the river saw daylight since entering Manchester, the rest having been culverted.
