Presently, I'm merely flushing out documentation and references regarding Giffen/ Giffin. This summer, I'll visit the Newville cemetery and get a photo of Catherine's tombstone. The St. Clairville library, I can visit. I also posted a inquiry on the Belmont County web site (www.rootsweb.com/~ohbelmon/)to purchase a used copy of Centenial History of Belmont County.
So, your information has been quite helpful. I have a great deal to do, when I next visit Mom. Thank you again.
