Since you relate this Jacob Waymire to Elizabeth Fuller, I think the date of his birth would be 3-17-1781 (not 1791) and died 10-17-1857. He is the son of John Rudolph Waymire (Johan Ludolph Wehmeyer). Jacob and Elizabeth were married in 1803 while still living in Randolp Co., NC. I am further descended from this Jacob through their son, Noah Waymire, who was born 1-23-1810.
