Paul and Anna Margaret Wolf were immigrants. I believe that both were born Ca 1730. I know that Paul was naturalized at the Frederick Reformed Church 10 Sep 1762 and that he died between June 28 and July 24 1775, based on the probate of his will. I have put very little research into the Wolf side at this point, but will let you know if I come across any additional information on the Wolf's.
As for John C. Carmack's date of death, he definitely died before 13 June 1803 as Sarah Carmack is listed as John's widow in Frederick County 1798 Tax Assessment. I am guessing that the date of 13 June 1803 was used as Sarah Carmack filed an Administration Account on 15 June 1803. 13 June 1803 is the date that I have seen in other documentation as well.
In the grand scheme, I am not sure if a few years matters. I am more curious as to where the information came from.
