In 1930, the High Street Christian Church [home of a Pilcher organ] and First Congregational Church voted to merge, which took place in 1931. They used the First Congregational building, and it was still used as a church by 1950.

The structure is still in place, but in poor condition with the steeples long gone. The organ may still be in there, but not sure.

This entry describes an original installation of a new pipe organ.

In late December 1902, the First Congregational Church on S. Center St. burned. It had contained ABF Opus 500 since the 1890s, when it was installed as part of a series of renovations and expansions.

The church was rebuilt in the same spot, and the new building was ready by summer 1903, and it contained ABF Opus 801. The church was apparently incorporated in 1930, and it is referenced in newspaper articles up to 1944, but I don't know what happened to it after that.
