According to the book Clay County Cemeteries, the Allen Morton Cemetery is located "2.3 miles from Bentree in Clay County, W. Va. on Rt. 16 then left 1/2 mile on dirt road."
This cemetery can possibly be confused with the Lizemores cemetery located in Lizemores, Clay, West Virginia, which is also referred to as the Morton cemetery. Furthermore, the town of Bentree, which the Allen Morton Cemetery is usually associated with, is sometimes said to be located in Nicholas county, while at other times, in Clay county.
In any case, just be aware, especially on death certificates in the early 1900's, that a burial listing of Morton cemetery in Lizemores, WV could be referring to either the Lizemores Cemetery or the Allen Morton Cemetery.
