In 1870-72, John Marius Wilson's Imperial Gazetteer of England
and Wales described Glenwhett like this: GLENWHETT, a hamlet in
Blenkinsop township, Haltwhistle parish, Northumberland; near
the Roman wall and the Carlisle and Newcastle railway, 3½ miles
W by N of Haltwhistle. It is separated by Tippal rivulet from
Greenhead village; and it has an inn, the garden-wall of which
includes a Roman altar. The location is where the name
"Glenwhett" appears on the Ordnance Survey 1:10,560 map of
Northumberland of 1865, accessible on the old-maps.co.uk site.
It appears to refer to the part of Greenhead east of the Tipalt
Burn. Additional information about this locality is available
for Greenhead A Vision of Britain through Time includes a large
library of local statistics for administrative units. For the
best overall sense of how the area containing Glenwhett has
changed, please see our redistricted information for the modern
district of Tynedale. More detailed statistical data are
