Gruesome stuff. I must stop playing with the NLS's maps site so much, but here's what they have. They've not been built on, which is probably very sensible given what I've just read, and appear to be waste land.
Here's the Abercromby Street one. If you switch this map to the 1850s OS one, prior to St Mary's Industrial Schools there was a convent next door, which may or may not be a coincidence:
>Map 1<John Street is now Tullis Street, and Green Street at the other side of the burial ground has partly been replaced by Landressy Place. The burial ground is marked disused by the time of the 1890s OS map:
>Map 2<(As an aside, though most of the buildings around the second one have gone, including Bridgeton Free Church, I wonder if that's the church hall still there?)
All the world seems in tune on a Spring afternoon, when we're poisoning pigeons in the park.
