My Comments notes for Margaret Kline
Her tombstone says died 1871 but she was not living with her husband in the 1860 or 1870 Census.
Margaret, interestingly, was a descendant of John David Mertz through his son Nicholas whose daughter, Catherine, married Lorentz Kline and they were Margaret’s grandparents.
