In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Thirlwall like this:
THIRLWALL, a township in Haltwhistle parish, Northumberland; 4 miles WNW of Haltwhistle. Acres, 7,944. Pop., 360. Houses, 65. T. Castle belonged to the Thirlwalls; gave a night's lodging to Edward I.; passed to the Swinburnes and the Howards; and is now reduced to a fragment of a ruin.
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 Thirlwall has changed, please see our redistricted information for the modern district of Tynedale. More detailed statistical data are available under Units and statistics, which includes both administrative units covering Thirlwall and units named after it.
