In 1896, Father Joseph Zebris of St. Andrew Church, New Britain organized the Sons of Lithuania Society in Hartford, offering Mass for the city’s Lithuanian immigrants in a rented room on Sheldon Street. 1900, when the mission filed a report with the diocese of Hartford, is officially regarded as the inaugural year of Holy Trinity Catholic Church. In 1903, the church purchased property on Capitol Avenue which included a two-story brick building which was converted into a place of worship. This brick dwelling was moved to the back of the lot in 1913 to make room for construction of a new church. The cornerstone was blessed on October 10, 1915 and a basement chapel was ready for use by Christmas of that year. The remainder of the church was completed in 1927 and was dedicated on March 18, 1928.
