[1] During a residence at Benwick Hall, near Hertford, he made extensive collections relating to the topography and antiquities of Hertfordshire.
These filled three folio volumes of closely written manuscript, which formed the nucleus of Robert Clutterbuck's history of the county.
Afterwards Blore lived successively at Mansfield Woodhouse, at Burr House near Bakewell, at Manton in Rutland, and at Stamford.
The latter borough he unsuccessfully contested[dubious – discuss] in the Whig interest, and he also edited for a brief period from 1809 John Drakard's Stamford News.
He died in London 10 November 1818, and was buried in St Mary on Paddington Green Church, where a stone bearing the following inscription was erected: Sacred to the memory of Thomas Blore, Gentleman, of the honourable society of the Middle Temple and member of the Antiquarian Society, whose days were embittered and whose life was shortened by intense application.
