W.W. Trent Papers from The West Virginia Archives and History located in Charleston, WV.
Here is the website: http://www.wvculture.org/history/archivesindex.aspx
There are also a couple of books and a Ph.D. dissertation on the early history of Education in West Virginia. I am providing some of the citations.
