Sister Marianne O’Neill was born on May 28, 1936, in Chicago, the youngest of three children born to David and Frances (Whitty) O’Neill. Her two older brothers were Whitney and David. The family lived on the South side of Chicago, just one block from St. Laurence Church.
In her autobiography, Sister Marianne wrote the following about her family and her early life.
My mom and dad were both born in Chicago. My oldest brother Whitney was born in 1927 and David, my other brother, was born in 1932. My dad worked at Carnegie Steel in South Chicago for thirty years. My mother did not work but when all of us were grown, she worked for Children’s Activities in downtown Chicago at Christmas time.
I loved all my teachers at St Laurence School. I went to Aquinas High School and graduated from there in 1954. Again, I had just wonderful teachers. At that time we had all nuns except for the drama and gym teachers. As you can see the only influence I had were the Dominican Sisters. I did have cousins who were BVMs and I saw them every summer but I never had the idea to enter their congregation.
