Amelia Harris Map of Area in Birmingham

I have been having a hard time locating historic maps of Birmingham. There is a Birmingham history forum that has the most generous members.  I posted for help in locating the address mentioned in yesterday's post.  Within an hour I got this map.  We cannot identify which court that the Harris family lived in but I think the map is very illustrative of the concept of Back-to-Back houses.

Remember to right click on the picture to make it bigger.  This is a map from 1890 but the forum contributor said it was the same throughout the 19th century and didn't change until the 1960s when they were mostly torn down.  It is was a densely pack block like the whole area.
