I believe the 400 block would be just north of Buttonwood Street. You can see "Black Alley" labelled on this 1860 Reading City Atlas. http://www.davidrumsey.com/luna/servlet/view/all/what/County Atlas/where/Reading (Pa.)/when/1860/1862?sort=Pub_List_No_InitialSort,Pub_Date,Pub_List_No,Series_No Important Note: The author of this message may not be subscribed to this list.
