An update for e-mail address:
Pearl,
I don't know if anyone else has reponded to your query but if not--- I believe that the parents of your Mary Elizabeth Knapp married to Abraham Shuman are Peter Knapp and Joannah Kiser(Keiser)/Knapp. This info comes from the Bible of Barbara Lewis/Knapp wife of Nelson Allison Knapp a brother of Mary Elizabeths. Other siblings are oldest to youngest: Harriet, Mark, Ann/Effie, Henry W., Nathan, (Nelson & Mary Eliz. are next in line), then Peter, JR. (my gggrandfather) and finally David. According to census records Peter Sr. was born in NY and Joannah in NJ. It is supposed that Peter Sr.'s father was a Jacob Knapp but I have been unable to find any connection. Peter Jr. and wife are buried in Marcy cemetery in Duryea, PA and other Knapps that are buried there include Zephaniah & son Joseph which would lead you to believe there must be some family connection. My own father always said that his "people" orginally came from Connecticut which that NE corner of PA was one time part of Conneticut. However, I live in Texas and rarely get back to the NE so research is super difficult. Will be happy to share any info I have and hope to hear from you.
