Much of the eastern side of Maple Grove is Webster or Webster-related. Sometimes I feel as though I'm somehow related to at least half the people buried there. There are also Webster-related graves in Evergreen Cemetery in Painesville and Williams Cemetery in Leroy.
I have a "map" of Maple Grove (done in MS Excel) and I've marked the location of the Webster and related plots. Almira Webster is buried in Section 66, lot 3, grave 2 (Dennis is in grave 3), which is next to the Erwin & Amanda Warren lot (65-4).
As I mentioned, Almira does not have a gravestone. She's listed in the sexton's records as Elmira Webster.
My father lives in Rock Creek and I get up there to visit a few times a year. Maybe when I'm in the area, we can get together to compare notes.
