Quite a bit to look up there!
However, the 1901 census gives references to the following at 47 Tower Street West, Sunderland (actually only 2 or 3 hundred yards from Rowlandson Terrace!):-
William A Hoseason, age 30, canvas tent maker, b. Sunderland
Margaret J Hoseason, wife, age 27, b. Sunderland
Eva Hoseason, daur, age 2, b. Sunderland
Ada Hoseason, daur, age 1, b. Sunderland
Speedings, the tent makers, is a well-known business that manufactures (as well as tents!) sails, ...anything canvas or its more modern nylon-type "containers" - a few years ago I had a bespoke cover made by them for a telescopic radio mast on a Landrover. I have no other connection with the firm!
They moved a few years ago from Monkwearmouth, north of the Wear, to a newish business park at Leechmere, about 2 miles south. Oddly enough, on the same business park, there was (and may still be) an engineering consultancy/business, run by, ISTR, somebody called "George?" Hoseason...
