Thomas Galberry, an Augustinian friar and former president of Villanova College, was installed as the 4th bishop of Hartford in 1877. Galberry only served for two years before an abrupt death but he was able to lay down the cornerstone of the original cathedral. Galberry was followed by Lawrence S. McMahon. McMahon had served as chaplain with the 28th Massachusetts. Under his leadership of 14 years, 48 parishes as well as 16 school parishes were established. The sixth bishop, Michael Tierney, helped with the creation of 5 diocesan hospitals.
