I also am researching this family. I believe I am descended from Joseph. I have the names and year of birth for all of John and Phoebe's children. Abigail b. 1787, d. 1859 married Asahel Ward Mary b. 1789 married John Crawley Hannah b. 1793 married William Kennedy John b. 1791, d. 1883 married Ann Teetzel William b. 16 Feb. 1796, d. 21 Mar 1854 married Martha Jane Cutler Daniel b. 1798 Joseph b. 1801 David b. 1802, d. 1862 James b. 1803, married Magdalena London Hiram b. 1805, d. 1874, married Rebecca Babcock Sarah b. 1807, married John Springsteen or Springstead Phoebe b. 1811 Abraham b. 12 Mar 1812
Since John was away fighting for the British during the war, most likely he never saw his youngest son, Abraham.
I have more information about this family. If you would like, please write to me at my e-mail address which is provided by this web site.
