Appears to be a child's grave - A few stacked stones - tumbled: 8615
Adult grave - stacked stones. Next to Frances Barrett. Is this the grave of John Barrett. Is his marked stone still there buried under the rubble. 8616
* This might actually be the footstone for Mary Carlisle. Someone recently moved it over to the foot of her tomb. 8640x

Spelling of Carlisle ("s" is silent) is all over the place so I will use the most common spelling "Carlisle" for all of the above.
How are these Barretts' connected to the Barretts' in the Center Hill Church Cemetery?

 Photographed on 4th Nov 2016. The inscriptions were corrected/updated with exceptions found or known by C. Wayne Austin. This publication culminated from various sources. First it was shown on page 183 in the book Bedford County Tennessee Cemeteries by Tim & Helen Marsh in the 1970s.Findagrave left off James & Elizabeth but I added them.
