Hi Andrea,
I have been told by the "Quaker Draper" descendants whose ancestors were from Perquimans Co. NC, that they did not believe in marking their graves. Ray Draper, a WikiTree member and I have been trying to find a connection between his Quaker Draper from Perquimans Co. and my North Farnham Parish Draper (Virginia).
He told me there are no Quaker Draper graves to be found in that county, evidently because they didn't mark them for whatever reason.
Ironically, Ray Draper's kin and my Draper kin married into each other, but not until the 1850s in Indiana, USA. A great great granddaughter from his Draper (with a different surname) married into my Draper.
I would bet you anything, the Draper in Perquimans Co and your Haskett have some connections. The Quakers married Quakers.
