In my family history, Jacob's dates were 1743-1830, and his wife Christena (Cooper?), 1753 - 1830's. Their son, David W. Berger (1790-1877) married an Anna Sutherland (1799-1872). David and Anna's daughter Susan Keziah Berger (1818-1907) married Rev. Jehu Hank (1801-1880). Their daughter Susan Ann Hank married Captain John C. Wiseman Morgan, who was killed in the Civil War (confederate side). I have a bit more information if you want to email me.
