1826: The 1983 booklet "Gunsmiths and Gunmakers of Bedford and Somerset Counties Pennsylvania 1770-1900" lists William Hohrson as a gunsmith and coppersmith in the borough of Bedford in 1826, with a value of $250.00. This individual is not included in the 1991 Whisker & Whisker book, or the 2001 Whisker & Yantz book, or the 2017 Whisker book.
I did not find William Hohrson in transcripts of the 1800, 1810, 1820, or 1840 census records for the borough of Bedford, or in the manuscript 1830 census records of the borough of Bedford. There is a phonetically similar "William Courson" in the Bedford town section of the 1810 manuscript census records of Bedford County.
