The historical residence which was unoccupied at the time of the fire was undergoing renovations, according to Robinson.

Built in the Civil War-era, James Buchanan "Diamond Jim Brady" purchased the home from a previous owner in the early 1900s.

It was one of the oldest, and most historic buildings in the township.

The building had a colorful history over the years; after Brady moved on, it was operated as a private residence, hotel, convalescent center, boarding house and summer camp.
