I will check my records, but I have run accros Levi Root's grave in Strafford, VT. I think in the Kibling Cemetery. One of my great-grandfathers was married to a Molly Brisco. I can check it out for you the next time I go up. I think that William may be buried there. If you want something quicker, you can write to the Town Clerk in Strafford and she has a list of people buried in Kibling that you can use to locate them. I have seen Levi's headstone though.
