Researched the information you provided in the "Descendants ofHenry Gibbel" I found the following:
Jacob Gibble - cannot find any Jacob that married a Barbara Hilton; however, did find a Jacob (1772 - 1839) that married a Barbara Eby (1779 - 1837).Any further identifying information?
Benjamin Gibble - am able to find a reference to this gentleman as marrying Mary Hilton.Lists they had 9 children, including one who died "in Libby Prison, Civil War."All of the children, except the one noted above have further references in the Genealogy Book.
Hope this is helpful.If you wish to follow-up, please get back to me and will try to help you out.
