Walking under the Albert Bridge towards the Transporter you first arrive in Queens Square, at the Old Bank or Cleveland Club on the corner of High Gosford St, Cleveland Street began, I think Durham st. began at the junction of East St, and at the railway crossing at Vulcan St. Ferry Rd. began and ended at the Transporter Bridge So my guess is that Durham Place would be a small yard or close between East Street and Vulcan Street on the right as you go towards the Transporter, there were a number of small yards and alleys along there before the Mechanics Hall and the Royal Pub.
Suffield st began at the junction of South Street and went westwards toward Stockton St, so to give it some perspective (I used to have the old maps) walking up Sussex st. from Bridge St the first on the left would have been William St. then a small entry near to St Mary's School then the next on the left would be Richmond St. you are now on South Street and then a small street called Henry St. next would be Suffield St. and finally West Street. if you were to continue on down North St. the next on the left would be Dacre St and the Commercial st.
Hope this helps
