Hi Bets123.
The website you linked to looks to contain loads of information about the inhabitants of Long Row and seems to answer all the questions you were asking.
Presumably the photo of the terrace of houses in Long Row is the same row that you are researching? It looks like a normal row of Victorian Terraces to me. I don't know if this is a reference to the same Row, but presumably it is because there are twenty of them, and they are still there today. The website says:
The land to the South of the canal (No. 27 on the 1852 plan) was given to William, whose sons sold it. Part of the land to the North of the canal (No. 25 on the 1852 plan) was laid out as a road (originally called Cowlishaw's Row, now Long Row) and all of the children got together and in about 1840 built a row of 20 houses, owning 4 each and the plot on the opposite side of the road on which two of them built a further two short rows of 4 houses each. Many of these were occupied by boatmen (see section on Soresby with photo). In 1891 Cowlishaw's boatman John Woolley lived here with his wife Charlotte and his grandson.
Is there a specific family who you are researching? If so, if we can find them at Long Row on the census, we might be able to see the neighbours also living in Long Row.
