Church of Ss. Peter and Paul to avoid confusion with another St. Mary's in Manhattan. The stained glass was by the Morgan Brothers, thus establishing a business relationship with Keely that carried through a number of projects. The church was demolished in 1957, when a new Ss. Peter and Paul was built. In 1846, Kelly married Sarah Farmer; they had seventeen children; ten of whom lived to adulthood. Two of his sons worked in his office, another became a successful musician, the fourth, a physician. Sarah Keely died in 1876. Architectural career The Church of Sts.
