I contacted Bond County Clerk and received a copy of original marriage record McHenry Johnson & Margaret Gilmore Nov 5th, 1820 by William Hunter.[Immediately below McHenry's name is a Benjamin Johnson & Rebecca Plant April 15, 1820 ... relationship to McHenry is unknown][Only 10 marriages conducted by William Hunter, Minister Methodist Episcopal Church in Bond County, IL between 1820-21]
Marriage record of McHenry Johnson & Nancy Rutherford, January 23, 1823 by Abraham Williamson, Bond Co, IL was a transcription. I did ask the clerk to pay particular attention to the year.
NOTE: Bond County, IL in 1817 was 26 miles wide and extended north to the "Wisconsin line"! Only 11 counties in IL at that time.
