Susan, it would help if you gave the surnames of your ancestors at Furnace Row as your doc is difficult to read.
Here is a section of a 1895 Map of the Colliery. Ive looked through my maps & none had Furnace Row on. The suggestion it could have been part of High Lane Row sound right as there were 2 shops registered for Furnace row.
Gill Christopher, Shopkeeper, 52 Furnace Row, Hebburn Colliery.
Southern John, Shopkeeper, 74 Furnace Row, Hebburn Colliery.
