Ukrainian Catholics first settled in Terryville in Plymouth in 1895. They did come directly from Eastern Europe but initially settled in central Pennsylvania before relocating to Connecticut. They established a voluntary association called the Rus Ruthenian Brotherhood of St. Michael the Archangel in 1902. Having worshiped in New Britain from 1896 to 1904, the Archangel St. Michael Ruthenian Greek Catholic Congregation then began holding services in a school on Main Street in Terryville. The congregation acquired land on Allen Street in March 1905 on which to build their own church. The cornerstone for the new church was blessed on July 4, 1910 and St. Michael Ukrainian Catholic Church at 35 Allen Street was soon completed. A sacristy was added to the north side of the church in 1944.
