This Hamlett Cemetery seems to be a mystery. After looking thru the census records, I've seen a number of Hamletts living in the area at that time so I'm guessin' I'm probably dealing with an obscure family cemetery or the LDS document is incorrect. The problem is, the document claims her life dates were recorded from her actual stone.
The area they were living in at the time was actually in Independence County, although a few years later much of that area became part of Sharp when it was formed.
Margaret Bizzell's husband John Logan Jones is buriedwith his last wife over in the Palestine Cemetery, which is just west of Cave City, but I don't believe it's 8 miles west of town and there's no record of her being buried there.
Oh well....looks like it's back to the grindstone.
