I found a great many references to the Giffen/in family in the following resources. Hundreds of other families are also mentioned. To date, I've only copied the pages. Each page (I copied)refernces a Giffen/in, in some manner. You may also find references to the families you are interested in. These books were at the Columbus library:
"Belmont County History 1988" published by Ohio Extention Homemakers Belmont County about 100 Giffen names only 17 Giffins also 29 Greelees eg Hugh Giffen, born 1834 married Isabelle Mcallister. They were members of the Rock Hill Presbyterian Church. They had nine children
eg John Wallace Giffin married Mary Ann Telliho. They have a daughter, Stephanie, who is a Junior at Thomas Jefferson High School (1988). They reside in Pittsburgh and John is a Sr. Financial Analyst with USX Corp. ________________________________________________________ "Belmont County - Old Home Coming", had a great deal of information regarding St. Clairsville and Belmont County families, but nothing regarding Giffen/ins. Gazette Press, St Clairsville, OH1910 _________________________________________________________ "Centennial History of Belmont County and Representative Citizens" published in 1903, compiled by Hon. A.T. Mckelvey
This is a hugh text which has a detailed history of early Belmont County. Also, a chapter on each township. I copied the entire chapter on Pultney Township and ech reference regarding a Giffen/in. _________________________________________________________ "History of Belmont & Jefferson Counties and Incidentally Historical Collections" By J. A. Caldwell, published by the Historical Publishing Co., Wheeling, WV 1880.
ABout 19 Giffen/in names are referenced. If anyone had a family member living in Belmont County and the served in the military, the information is here. Much of it references the Civil War.
