"Thomas Archer... was one of the two founders and one of the first two elders of the Covenanter Church in 1810."
"Accordingly in the summer of 1810, [Rev. John Kell, from Chester, South Carolina, a young minister of the Reformed Presbyterian (Covenanter) Church] made his first visit. During that visit Samuel Hogue and Thomas Archer, a former member of the Seceder Church near Chester, South Carolina, accepted the faith and practice of Reformed Presbyterian Church, and with their families constituted a "Society" for prayer and religious conversation. This was the foundation of the Reformed Presbyterian (Covenanter) Church in Princeton. It was this church which, after almost three-quarters of a century of turbulent existence, accepted the principle of nation-wide union of the two denominations and coalesced with the local United Presbyterian Church to form the First United Presbyterian and later the United Presbyterian Church of Princeton."
