There is a very interesting article - "The Lanes, Alleys and Quays of Old Sunderland" by C B Walker in "Sunderland's History No 5" - the journal of the Sunderland Antiquarian Society. The list contained in the article was compiled from the early records and runs to thirteen A5 pages. Unfortunately it does not include any references to the current queries on "streets within roads", however it may be a useful article to refer to on occasions. Alan Vickers.
