Peter`s grave & his wife`s Judith are on findagrave.com. According to that it is an Episcopal Church Cemetery. Unless the church took over an old family plot, or old Quaker Cemetery,I dont see how a Quaker would be buried in an EC Cemetery do you?
Thus far, I havent found any online burial records of William. I remember reading the will on Ancestry.com that another member there had posted, and I believe it listed his name spelled both ways and it making it clear that his last wife Bathsheba and their son Benjamin to be taken care of, etc. That Benjamin ( b. 1778 )was reported to have died sometime between the 1830 & 1840 Census`s which would have made him between 50-60 y/o thus not making him young. His wife Hester Overs does have a listing on Find a grave, but no picture. I havent had a chance to make it to Zanesville, OH,to see it for myself ( and check cemetery records ), and I wouldnt be too suprised to find Benjamin Jr is buried there as well.
His son William was born in 1799 ( my GGG Grandfather ) and his daughter Mary was born in 1810, both in PA. Both married near Zanesville in the 1820`s before moving the next decade, and like I said the 1840 Census shows Hester as a widow and head of household as she remained until her death in 1866
The family pictures I have are from the late 1880`s and possibly first couple of years of the 1890`s. Long after Benjamin Jr ( c. 1840 - or before ) and his son William ( 1872 )had died.
