Beckfoot is on the coast, about 40 miles away from Stapleton. It seems unlikely that someone would be buried so far away from where they lived unless that was the nearest Friends burying ground. On edit: close examination of the gravestone in the photo reveals that the inscription says "in affectionate remembrance of Thomas Little of Bitterlees", which is about 2 miles from Beckfoot. The style of the gravestone makes it much more likely that it's from the early to mid 1800s than the 1700s.
