Arthur Joseph 'Art' Rooney, Sr. (January 27, 1901--August 25, 1988), often referred to as 'The Chief', was the founding owner of the Pittsburgh Steelers American football franchise in the National Football League. Rooney's great-grandparents, James and Mary Rooney, were Irish Catholics who immigrated from Newry in County Down, Ireland to Canada during the Irish potato famine in the 1840s. While living in Montreal, the Rooneys had a son, Arthur (who would become Art Rooney's grandfather). James and Mary later moved to Ebbw Vale, Wales, where the iron industry was flourishing, taking their son Arthur, then 21, with them. This Arthur Rooney married Catherine Regan (who was also Irish Catholic), in Wales, and they had a son, Dan. Two years after Dan Rooney was born, the family moved back to Canada and eventually ended up in Pittsburgh, Pennsylvania in 1884. Along the way the family grew to include nine children of which Dan was the second.
