Hi there,if you type Soho Hill into the search box at the top of the page quite a few threads come up with pictures of Soho Hill.
Bristol Road,Edgbaston,where I believe the Selkirks lived,was quite upmarket!There were quite a few large houses there in the earlier part of the century.
I believe Wellington Road (the Edgbaston one or the Handsworth one) was the same sort of housing.
Do you mean Lozells (Lazells)?
As I say type any of the roads into "search" at the top of the page and quite a few posts come up,some with pics.
For an up-to-date view have you tried google street view? There are still some of the older types of housing on those roads and I find "street view" quite good.
