Marie was born and raised on the west side of Chicago to Dennis and Mary, nee McCarthy, Sullivan, natives of County Kerry, Ireland. Marie was a woman of deep faith who always had the door open, the kettle on, and Irish soda bread ready to be served. She will be deeply missed. Funeral Tuesday, prayers at 10:15 at Cooney Funeral Home to St. Zachary Catholic Church. Mass at 11:00am. Interment All Saints Cemetery. Visitation Monday 3 to 8 p.m. In lieu of flowers, masses preferred.
