アメリカ合衆国長老教会
The Presbyterian Church in the United States of America was joined by the majority of the Cumberland Presbyterian Church, mostly congregations in the border and Southern states, in 1906. In 1920, it absorbed the Welsh Calvinist Methodist Church. The United Presbyterian Church of North America merged with the PCUSA in 1958 to form the United Presbyterian Church in the United States of America (UPCUSA).
