When the disruption took place in 1843, Rev. William Logan and the North Church joined the Free Church of Scotland. Almost immediately on joining the Free Church, the Rev. William Logan received a call to Sanquhar Free Church, and in June 1843, at the first meeting of the Free Church Presbytery of Lanark, decisions were taken; firstly, to unite the North Church and the congregation that came out of the Church of Scotland to prevent there being two charges of the Free Church in Lesmahagow when many parts of Scotland had no provision and secondly, to preach the North Church vacant since the church building was too small for the Free Church membership now in Lesmahagow. That presbytery was constituted by Rev. William Logan (Moderator), Rev. Thomas Stark of Lanark and Rev. Dr. Andrew Boreland Parker and an elder from each congregation.
