The Andover Ecclesiastical Society was officially formed in 1748, when it also settled its first pastor, Rev. Samuel Lockwood, who served until his death in 1791. Once the Society was established, construction began on a meeting house on what is now Hebron Road, which took twenty years to complete (although it began to be in use before it was finished). A new church was built in 1832-1833, which was later renovated in 1869. The First Congregational Church was much expanded with a new addition in 1958.
