I believe that Mary Raker would be the daughter of Jacob Roecker or Raker, the son of Hans Martin Roecker who emigrated in 1766. Jacob would have been born around 1769 in Montgomery Co. He may have spent some time in Northumberland Co- where some of his siblings set up residence, and eventually moved in the early 19th century up to Tioga County. I am interested in any information anyone has on his other children. I think he had Jacob Jr., John, Mary, Rebecca, Daniel, and Sally.
