Yes - that is where Dick Groat went to school.
I think Dick Groat went to Edgewood HS. It and Swissvale now are part of Woodland Hills, along with Churchill, Braddock, North Braddock Scott, Rankin and Turtle Creek.
I remember the first of what would later become an avalanche of mergers: Keystone Oaks replaced Dormont, Castle Shannon and Greentree. The name came from the key to the door, the stone from the castle and the oak from the tree.
Wilkinsburg still exists. In the City League, there are so many gone I can’t recall all of them. But, Fifth Avenue, Schenley, Peabody, Oliver, Allegheny, and, I believe, both of the vocational schools, Connelly and Washington, are gone. Probably some of the schools on the South Side and in the West End are gone too.
Also, much to the chagrin of Rifleman, Stefan Djorjovich and others, Ampipe is gone.
Of the WPIAL school we played when I was in HS (right after the invention of electricity), the only one still open is Wilkinsburg. All others have been replaced with mergers.
