There were three Makrauer's in the Barber business in Pittsburgh around the turn of the century. Daniel Makrauer, probably the father, was at 5 Market from 1897 until 1901. Charles, was at 523 5th Avenue from 1897 until 1898. In 1897, Daniel and Charles both lived at the same address. In 1899 only, The Makrauer Brothers (Andrew & Charles), were in business at 6 Smithfield. I don't know the relationship of Z. Makrauer to those listed in City Directories.
