You might want to take a look at the orientation of the 5 depressions.
Christian burials are typically laid out east-west give or take a few
degrees. That's not to say that trees weren't planted in a similar fashion,
but it's another free piece of the puzzle.
Probing would be another inexpensive method. Often, it is possible to
"feel" a grave by probing. We use a 3/8" steel probe with a slightly larger
diameter ball tip. Areas that have been previously excavated probe with
somewhat less exertion than immediately adjacent ground that has not been
disturbed.
Hiring a cadaver dog and handler might be more expensive than GPR study of a
relatively small area. Most cadaver dogs are trained to scent decaying
remains and not just bone material. Unfortunately, there may be little else
left of a 150 year old burial. However, dogs that have been imprinted with
human skeletal material are known to have been successful locating unmarked
19th century graves consisting of little more than bone under some
conditions.
For what it's worth, it has been our experience that a greater degree of
ground outgassing occurs during a sharply dropping barometer, and that this
condition significantly enhances the animal's ability to scent deeply buried
remains. Also, permitting the cadaver dog access to a freshly probed hole
and the tip of the probe may confirm unmarked burials. There are numerous
other variables as well including the amount of decay, coffin material. soil
type, ground moisture, ambient surface conditions, etc. We made use of a
cadaver dog on a number of cemetery delineation projects for several years
until it died last year. I have personally witnessed the dog detect small
human bones (multiple carpal, metacarpal and a calcaneus) near the surface
though not visible. There was clear evidence that these bones had been
excavated from mid-19th century grave(s) by groundhogs or other burrowing
critters before being scattered by plowing. I have also watched the same
dog fail to locate any graves at all in a marked cemetery. The use of
cadaver dogs to locate older graves is by no means infallible.
Seems like a preponderance of the available evidence including grave-size
depressions oriented in a row cemetery fashion, taken with some probing and
the other historical evidence you already have, should be enough to red flag
the area for the probability of unmarked graves.
Good luck,
