I don't know if this is the same person, but when I saw your message, I thought it would be at least worthwhile to check out the coincident.
My grandfather, Samuel Lee Bookout, bought a family plot in Stilwell, OK, where he and my grandmother retired. Somehow, in the mid 90's, a man by the name of Robert Lee, Lee being the last name, was buried in the middle of the family plot.
I'm sorry that I do not have dates or even the exact name of the cemetary (it may be Taylor or Tyler Road, but the abstract office in Stilwell could tell you for certain. Or even one of the funeral homes.
I couldn't be sure that it is the same Robert Lee, but the coincident was just to odd to overlook!
