The following info was posted on the Irish-In-Chicago mailing list. I'm not researching this surname...just thought it would help someone searching Feehans in Chicago or Tipperary.
Patrick Augustine FEEHAN (1829-1902). The first Catholic archbishop of Chicago was born in Killenaule, Tipperary IRL. While he was training for the priesthood, his parents left famine-plagued Ireland for America. The young seminarian eagerly seized an opportunity to join them in America and completed preparation for his 1852 ordination. As a curate in three St. Louis churches during the next few years, Father FEEHAN earned the title "priest of the poor" for his good works among those in need. During the Civil War, he tirelessly sought to comfort the wounded of all religions, and as Bishop of Nashville, TN, in the post-war years, he reconstructed the war-torn diocese by rebuilding churches, establishing schools, a convent, and an orphanage for the children of soldiers who had died in the war. In 1880, FEEHAN was elevated to archbishop of the newly created Chicago archdiocese, which thrived during his 22-year administration.
