Elgin was formed out of the western part of Concord Township, in the winter of 1876, comprising about a mile square. A sawmill and a grist-mill were established on the creek at a very early day by Joseph Hall, and the place became first known as Halltown, on the advent of the railroad it became Concord Station, and when incorporated became Elgin. A very attractive cemetery is maintained. The Methodists organized a class near by in 1854 in a school house; in 1858 removed to Elgin School House, later to the Disciple Church. They later bought the Presbyterian meeting house at Beaver Dam and moved it to the borough.
