I have also found all these Jeremiahs confusing, but I think I may have them sorted out. Jeremiah b: c1730 wed Eliz. Evans 3-3-1750/51 and had 3 children. Jeremiah b:c1748 d: 1808 wed Betty Lawless c1766 and had 13 children. Jeremiah b:c1770 wed Magdalene Sallee 4-11-1797 and had 7 children. I don't think the first marriage date of 1750/1751 is correct, but I can find no other date.
