| Administrative History | The Peak District Mines Historical Society has indicated that whilst the Holme Hall Chert Mine was being
actively worked in 1853 (ref: Mining History Vol. 19 No. 6, p.75), it is also known that Robert Thornhill was producing chert from his land on Longstone Common from the end of 1803 to May 1816 (ibid. p.111, Table 8). Therefore it is believed that the volume under reference D6967/7/3 does not relate to Holme Hall Chert Mine. |
