Some Background

There is some uncertainty about the parentage of Isaac as there is a question regarding the biography of Isaac Ferguson as it has been presented in Everts, “History of Clermont County”. A 1991 letter written by Richard F. Oyler to Aileen M. Whitt regarding her compilation of Clermont County’s Vol. I, Revolutionary War Veterans: “… I cannot find anywhere his status as an officer amongst Military records. I have found evidence that he was a Private serving from Nottingham twp, Washington County, Pa. Most of the written texts of his Military service seems to come from one source: “History of Clermont County by Everts”. Most of the written word about Isaac came from the mouth of Ira Ferguson, a grandson and was written about 1880, a hundred years following the Revolution. I am grateful to Ira for the History that he was able to give to all of us, but perhaps over the years of telling and retelling it might have been embellished. Some of the genealogy given by Ira might be in error. Much research has been given in regards to his father. Clermont history says (his father was): Thomas Ferguson. A number of us believe that it is James Ferguson. Most of our evidence is based on the Will of James Ferguson of Nottingham twp., Washington County and a Deed from Loudin Co. Va.”
Mr. Oyler provides a photocopy of the basic record of military service for one Ferguson, Isaac, Pvt. he received from the Commonwealth of Pennsylvania.

The Ferguson history and genealogy that Mr. Oyler disputes is also found in: J. L. Rockey and R. J. Bancroft, History Of Clermont County, Ohio, Chapter XIX, Distinguished Men Of Clermont County. 1880 (Transcribed for Genealogy Trails by Heather Turner – and TMG Source #765.)8,9,10
