PITTSBURGH, Pa. (WKBN) – One of the sons of the late Pittsburgh Steelers founder Art Rooney Sr. and the brother of Steelers President and Chairman Dan Rooney has died.

According to the Steelers, both Patrick and his twin brother, John, grew up on the North Side of Pittsburgh. They were born six years after the funding of the Steelers’ franchise.
