Hi Matthew,
From a couple of sources on the internet,
Two Steps Fish & Chip Shop opened in 1895.
This would tie in with James Bolton in 1891, being a Table Knife Cutter(Cutler??) living on Franklin Street and the already referenced 1901 census showing James Bolton residing at 249 Sharrow Vale Road, occupation Fried Fish Dealer.
In 1911 if I have the correct James Bolton, he was a Tea Agent in the grocery industry.
