Description:
As far back as 1675, when South Ulster had not even one Presbyterian Congregation in either Fermanagh, Monaghan, or Cavan, there was a minister, Rev. Jacques in charge of the Corboy church. Rev. John Mairs of Loughbrickland was "transplanted" to Longford in 1697, where he complained about his work and the extent of his charge, "being at least ten miles over, and the two places in his charge (Corboy and Tully or Clongish) for preaching in each other Sabbath, being five miles distant".
