Christine,
Further to my last comment, the building shown as Fogridge on the Tithe Map (1840) is definitely Low Fogrigg. The tithe map doesn’t show High Fogrigg. The first edition of the Ordnance Survey 6″ map (1860) shows both.
Low Fogrigg was sold in 1921 as part of the ” Hardriding Estate”. The sale documents are at Northumberland Archives at Woodhorn (ref CLAS/126 ) and include a map.
There is an inclosure plan of 1783 (Ref NRO 00309 ) which you can view on the Northumberland Archives website by searching the catalogue for Henshaw. It shows Low Fogrigg (owner Sir T. Clavering) but doesn’t name it.
but doesn’t name it
