When the well-equipped task force arrived on a recent Saturday morning, the tangle of scrubby bushes, trees, briars and tall grass atop a little hill was scarcely recognizable as a cemetery from the nearby dirt road. When the 20 volunteers left, monuments of the Nichols family’s past had re-emerged into the noon rain. A Bulloch County Historical Society representative was able to revise his count of graves in the Nichols Cemetery from 29 to 39, and Dylan Green had completed all the steps but some paperwork toward becoming an Eagle Scout.
