St. Joseph's Church, the oldest Roman Catholic church still standing on Staten Island, is located on Poplar Avenue in Rossville. St. Joseph's was founded on July 2, 1848, by Father Mark Murphy, pastor of St. Peter's Church, when he celebrated Mass for 58 Catholics in a house on Rossville Avenue as a mission of St. Peter's parish. In 1851, a small chapel dedicated to St. Joseph was completed on Poplar Avenue. When Father Francis DeCaro, O.F.M., was appointed as first pastor in 1855, St. Joseph's became an official parish — the third oldest of Staten Island's 36 parishes after St. Peter's and St. Mary's.
