In the early 1930's, St. Bernadette became a mission church of St. Patrick in Hubbard, OH. A small wood framed house was rented in October 1934 for Mass. Three years later, Bishop Joseph Schrembs, of the Diocese of Cleveland, decided that the mission had sufficient membership to establish a parish. On July 8, 1937, St. Bernadette was founded. On September 15, 1940 groundbreaking for the Locust Street building was done. One month later, October 27, 1940, the cornerstone was blessed and put into place in the basement under the sanctuary by Bishop James McFadden, the first Bishop of Youngstown. The parish completed construction by the Feast of the Immaculate Conception, December 8, 1940.
St. Vincent de Paul began in 1879 as a mission from the parish of St. Edward on the north side of Youngstown. In 1902, the misssion was closed, yet Catholics few in number, still met in their homes for prayer and fellowship. In 1932, the St. Vincent de Paul Society of St. Rose parish in Girard decided to restart a parish mission in Vienna, because of the growing number of Catholic families that had to travel to Girard for church services. Bishop Schrembs of Cleveland was so impressed by the faith and determination of the Catholics in Vienna, he made it a parish rather than a mission of St. Rose. The newly formed parish was given the name of St. Vincent de Paul, after the Society in Girard who rekindled the desire to take care of the spiritual needs of the Catholics in Vienna. Fr. James Gaffney became the first pastor of the parish on August 22, 1934. The brick church structure completed in 1950 has now been converted into a funeral home when the current church was dedicated in 2016 on the Feast of St. Thomas the Apostle on Sunday, July 3.
