I've just found an obit dated 15 Nov 1839, in the Nottingham Review:
DIED: On Wednesday week, in Mansfield Workhouse, aged 70 years, Benjamin Armstrong, framework knitter"
-- which I think confuses the issue a little as we don't have a note of a FWK before this. Does this mean that Benjamin the stonemason, husband of Ann, died somewhere or someplace else?
Another obit: Nott Guardian, Thurs June 30 1859: At Mansfield, on Tuesday week, aged 83, Ann, widow of Mr Benjamin Armstrong.
There's the summary of the inquest held on William Armstrong's son Henry (Nott Mercury, may 5 1848), the verdict from which was "Died in consequence of being accidentally crushed by a stone roller".
Another obit: Mansfield reporter, 13 Jan 1893: DIED: On the 9th inst, at Keir's buildings, Mansfield, Frances, widow of William Armstrong, aged 84 years.
