The men of Division I name their division after the Most Reverend Philip M. Hannan, thirteenth Archbishop of New Orleans. Having served the Archdiocese from 1965-1988, Hannan was a former Chaplain in the US Army 82nd Airborne Division during the Battle of the Bulge and was Auxiliary Bishop of Washington, D.C. before coming to New Orleans. While Archbishop of New Orleans, Hannan oversaw the integration of New Orleans’ Catholic schools, established a major Catholic television station in New Orleans, and crowned his efforts with the visit of Pope John Paul II to the Crescent City in 1987. Still active in retirement, Hannan continues to oversee his communications network, WLAE-TV. The Ancient Order of Hibernians named Hannan as its Man of the Year in 1991 and continues to derive inspiration from his energy and spirit.

Division I comprises all members who live within the corporate limits of the city of New Orleans.
