History of Third Garvagh Presbyterian Church
This congregation split from Main Street, Garvagh in 1809 over Regium Donum.
In 1863 this congregation together with Ballylintagh & Benvarden was received into the General Assembly as Third Garvagh, a member of Coleraine Presbytery, but this caused a split in the congregation, those who objected to this union leaving to join the Reformed Presbyterians.
