I'm a bit late in the day on the subject but new to this
Proktors Buildings. like Scott's Row, Veatch's Buildings and Scott's Buildings previously mentioned, were rows of tenements built on the hill between Pipewellgate and High Level Road. The houses on each were linked by external staircases, either wooden or stone flagsones, and each "landing" had a cold water tap and an earth or ash closet. (Health and Safety eat your heart out).
New Chatham was an area at the west end of Pipewellgate, under the present Metro bridge. Probably named by someone who had a business there and who originated in the London area. I remember New Greenwich and New Deptford to the east of the Baltic.
The reason for Askew Road having "no houses" (as mentioned in another post) was because the Greensfield Locomotive Works, which had its northern boundary on High Level Road, had its southern boundary on Askew Road. Last time I looked, the original boundary wall was still there. However, further west of the Works, houses were being built on, and branching off from, Askew Road in the 1870s.
Hope your aunt wasn't too mortified - there were some good folk came out of Pipewellgate
