My last name isn't Holt, but I named my wonderful old octagon house for the builder of the house - William Harrison Holt. His son, Pliny, went on to work for his uncle Benjamin Holt. He was an engineer and worked a lot of inventions for Holt Tractors which later merged with another company to become Caterpillar, Inc. Some of the same family still own Holt Cat in Texas. I was contacted yesterday by somebody writing a book on the family, it seems roles have been reversed as I always thought of myself as a researcher on the subject, not the expert to ask for information! But I guess I have become an expert on the Holt family when they lived in Granite Falls and built this house. This is a picture of Pliny at about the age he would have been when he lived here.
