Regarding Fr. Samuel Mazzuchelli, O.P.. Samuel Mazzuchelli was born in Milan in 1806 and became a priest with the Dominican order at age 17. Five years later, he moved to the U.S. and was assigned by Edward Fenwick, the Bishop of Cincinnati, to be a missionary priest serving what was once the Northwest Territory, which included Ohio, Michigan, Indiana, Illinois, Wisconsin and part of Minnesota. Fr. Mazzuchelli died of pneumonia in 1864.
In 1847, Fr. Mazzuchelli established a community of Dominican sisters in Sinsinawa. In 1918, the Sinsinawa sisters opened Rosary House, an all-girls high school in this suburb west of Chicago. The school would be renamed Trinity High School in 1926 when it moved into this building.

On a cold winter day in February of 1864, Fr. Mazzuchelli was called to visit the home of a dying parishioner. Knowing the seriousness of the need, he left without his cloak. Upon returning to his rectory in Benton, Fr. Mazzuchelli developed a severe case of pneumonia, which would prove fatal, and he died on February 23, 1864, at the age of 57. His dying words were from Psalm 84, which is included in the rite of the dedication of churches and altars.(Submitted on August 18, 2025, by Sean P. Flynn of Oak Park, Illinois.)
"How lovely your dwelling, O Lord of hosts! My soul yearns and pines for the courts of the Lord."
