One of the sections of this cemetery is the famous "Sedgwick Pie",
the family plot of Theodore Sedgwick and Pamela (Dwight) Sedgwick.
The best coverage I've seen of it is by "The Cooks": Sedgwick Family Plot.
It has disappeared from its old URL, so I have copied it here unitl I can find it again.
To their information I wish to add but one photo:

There are several other Sedgwicks buried in this cemetery but not in the plot; some are also descendants of Theodore, some are "cousins." I'll document them here.
