The congregation of Rothesay Free Church, which sat within the Presbytery of Dunoon, was established in 1843 at the time of the Disruption when the minister and the entire congregation of the Gaelic Church in Rothesay adhered to the Free Church. Worship continued in their own church until 1858 when they were required to vacate the building and temporary premises were instead provided until a new church was opened in 1860. Following the union of the United Presbyterian Church and the Free Church of Scotland in 1900, Rothesay Chapelhill Gaelic Free Church became Rothesay Chapelhill United Free Church and during this time Gaelic services ceased and the congregation lost their church and manse to the Free Church (continuing). A new church was built in the High Street and a new manse was purchased at a cost of £850. Upon the 1929 union between the United Free Church of Scotland and the Church of Scotland, Rothesay Chapelhill United Free became Rothesay Chapelhill Church of Scotland and in 1931 the name of the congregation was changed to that of Rothesay St James's. In 1938 Rothesay St James's was joined with the charge of Rothesay Trinity and the former St James's church was sold in 1939 to the Territorial Association. After this local union the congregation continued under the name of Rothesay Trinity and further union followed in 1979 with Rothesay West. The congregation of Rothesay Trinity sits under the jurisdiction of the Presbytery of Dunoon.
