Charles Conaty grew up in Worcester, Massachusetts and graduated from The College of the Holy Cross in Worcester, Massachusetts, in 1912. Ministry was a common factor in the Conaty family; a cousin was a Catholic Bishop, and Charles Conaty was following in the footsteps of his older brother who was a priest. He attended Holy Cross College in Worcester, Massachusetts, and received his theological training at the North American College in Rome. He was ordained a Catholic priest on September 17, 1915. He entered military service and was commissioned as a U.S. Army chaplain on January 5, 1918, serving at Fort Hancock in Augusta, and then during World War I with the 28th Division in France. Before going overseas a friend gave him a little black book to record his experiences. After the war this became the basis of a column titled “”My Little Black Book” that appeared in issues of the Catholic publication “Southern Cross” and in “The Catholic World.”
