My husband and I recently purchased an 1879 Victorian home that has two fireplaces. One of them has the initials "K.I.P." prominently stamped into the concrete inside the fireplace. We would like to know what this is - does anyone out there know of any such convention? Did families have their monograms imprinted into fireplaces when they were built? Is it more likely to be the builder of the fireplace? I have done some research online, but so far haven't found anything. The house is in St. Paul, MN. Any insight would be much appreciated.
