The Domesday Book
The Domesday Book of 1086 is available online but unfortunately there is no speciific entry for Mellor.
There is a general description of the area however which says that All Longendale is waste woodland, unpastured, fit for hunting
which fits the bleak inhospitable upland characteristic of much of Dark Peak even today.
does has an entry however, the name being recorded in 1086 as Lodeuorde
