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.

Visitation Monday 3 to 8 p.m. In lieu of flowers, masses preferred.

No matter how much time passed between visits, Mrs. O'Brien always welcomed me with a big warm kiss and a hug that made me feel so loved and cherished. I know you were greeted with the same warmth and love meeting Jesus in Heaven. One day we will all be together again, and until then we will remember your beautiful spirit. Love and big kisses, Laura Jamieson and family.
