Julia Greeley was born a slave in Missouri. After Missouri abolished slavery she moved to Denver, Colorado where she worked for the family of the first governor of Colorado. She became Catholic in 1880 and developed a deep devotion to the Sacred Heart of Jesus. She devoted her life to helping anyone who needed assistance. She would give to others from her own meager earnings, any anything she couldn't afford she would beg for. She was a daily communicant and a prayer warrior. At least one couple overcame infertility through her prayers. She loved children and would organize days in the park for children who didn't have the opportunity. One special ministry was to firefighters. She would go around every First Friday — the day of devotion to the Sacred Heart — and bring pamphlets about the Sacred Heart devotion to all of the firehouses in Denver. She died on the feast of the Sacred Heart in 1918. She did so much good for so many that her funeral was massive. Her cause for canonization opened in 2016, when her body was exhumed and reinterred in the Cathedral Basilica of the Immaculate Conception in Denver. She is the only person buried in that church, which opened in 1912.
