The Conway Block is at 301 High Street having been built and designed from 1884 to 1889. Martin Conway a dealer in pianos was here. The building is very large as the footprint far onto the side street.
By 1900 and up to at least 1915 this was the Murlless Block and housed two dentist and a dental supply company. Woolworth was also here at that point. Daniel Murlless appears even in the 1869 directory.
