Your mention of Schoharie County is the first reference I have seen which may begin to extend my line. My father, gf, and ggf lived there and in adjoining Montgomery County. However, I have been unable to find anyone else with a Neville link to this part of New York State. Prodded by your posting I did a web search and encountered some excellent work by the historians of Schoharie County. They have posted on line a history of the county covering the period 1713 to 1882 entitled: HISTORY OF Schoharie County, NEW YORK, WITH Illustrations and Biographical Sketches OF SOME OF ITS PROMINENT MEN AND PIONEERS. By William E. Roscoe. The web site is: http://www.rootsweb.com/~nyschoha/roscoes.html In the history of the town it is noted that the founder had immigrated from NJ perhaps establishing a relationship to NY Nevilles who may have followed. The excitement came when I read the following: "Theodore Nevills commenced the same business (mercantile ed.) here and after a successful trade of six years, a conflagration swept his property away together with adjoining buildings which have not been replaced." By inference I conclude this Theodore to be in my line as my gf name was Theodore John Neville and ggf John Nevill(e). It is fascinating to ponder why and how the name evolved during this period. Especially since the grave marker for my ggf has Neville on one side with the date of death and Nevill on the other when the plot was first established (I presume). Anyway, this may help in your search for information for Schoharie County.
