A bit of history for 75 Rathbone Street: there is an item in the Liverpool Albion, 28th September 1840 announcing the establishment, at that address, of a "Benevolent House" run by the Liverpool Society for Reclaiming Unfortunate Females. Inmates were instructed in “the employments of Dressmaking, Millinery and Plain Sewing”.
Here is a side-by-side map view showing where Rathbone Place was alongside a modern map. If you know Liverpool this should all make sense.

Roscoe Street is running north across Knight Street and is still there today; Rathbone Street is running south from the offset junction. You can see from the modern map that Rathbone Street has been replaced by the modern development beside the Anglican Cathedral. You can zoom and scroll on this map view.
The newspaper item that I mentioned above says that number 75 is "the third house from Upper Parliament Street", so if you scroll down in the map view, following Rathbone Street all the way to its southern end you will reach that area, and the junction with Upper Parliament Street.
