Historical Significance:

"When Wilbur T. and Rhoda Stephens Johnson built their elegant residence at 821 Main Street in 1895, it was at the southern edge of a group of fine homes that abutted the business district. They could not have foreseen that in less than 100 years, in the march of commercial "progress," most of their neighboring dwellings would have disappeared, leaving their home the "last of the Main Street mansions."
