History & local legend
The sandstone house above Tenmile Creek near Clarksville was the home of United Mine Workers reformer Joseph 'Jock' Yablonski, his wife Margaret and their daughter Charlotte. All three were murdered there in December 1969 after Yablonski challenged the union's leadership.
The house had already been the scene of a fatal confrontation. On January 30, 1939, when it served as a boarding house, Pennsylvania State Police Corporal George Dewey Naughton was killed while approaching an armed man barricaded upstairs. A local historian later recalled seeing a bullet scar in the stair rail.
After the Yablonski killings, stories circulated about screams, gunshots and blood appearing on the walls of the boarded-up house. A contributor recalling those rumors in 2010 described them as stories told in the community, rather than encounters the contributor had personally witnessed.
