I have reconstructed Jeremiah's family from the following 3 families found in the 1880 Census of Belpre, Washington Co., Ohio. It is of great concern that this this census record says his father is from Baden and his mother is from OH. I have no idea if this is the correct family. The birth date is good and location is good and there were documents in Meigs signed by Jeremiah and Susanna along with Benjamin and Mary Ollom. Still it's just guessing at this point.

Benjamin is listed as born in NY. His parents are supposed to have been born Father in NJ and Mother in NY. Nancy Jane's parents birth locations are an exact match for Benjamin's. The children have blanks for the Father's information. Need to see the original records.
