Marguerite: I saw Michael Bartholomew's reply to your query and responded to that. A daughter of your Jacob b. 1806 is Anna Elizabeth Werkheiser, b. 11 Sep 1830, d. 1906 per the Fritchman family tree. She married an Amandus or Remendus/Remendez Fritchman and had 6 known children. They are listed on my response to Michael's message. This is not a direct line to me, but I can put you in touch with Fritchmans who can provide more information.
