I’ve just rediscovered the Thomas Armstrong, beer retailer, living in Dipton in 1891, as found in your earlier thread linked above in reply#5. This is the family with the son Robert, baptised 1868 Throckley.
Where does this family fit, in your opinion? Why is this not the Armstrongs of Dipton at this time? And if it is, have you tried to trace them backwards?
This is the 1891 enumerator’s sequence:
Storfords Houses
Hopper's Nook
Marquis Houses
Gardeners(?) House
Smith’s Houses
Johnson Houses
Front Street, Fox Inn
Front Street
Todd's Houses
Wilkinson Houses
There are six households at Smith’s Houses, the first listed being Thomas Armstrong, 48, born Burnopfield.
