Hi Heather, It depends on what you mean by the "Bishopwearmouth area"? Historically south of the river was Bishopwearmouth parish, which over the years was formed into other parishes starting with Sunderland parish in 1719. Tatham Street would be in St. Paul's parish after 1854. You can see the parish boundaries of 1831 at http://aesica.dur.ac.uk/pip/singlezoom.asp?img=p2379&ref1=2250 Stan
