The once widely-known and choice variety originated just west of here, on a farm occupied by John Gilkey, 1798-1826. A brother, James, was fellow-worker. Their potato was also called Mercer or Gilkey.

Maps this old were drawn largely by eye, so places on them can sit miles from where they really are. The pin is ours and marks the marker's location today.

Example

For example, one family's tree showed the Articles of Confederation marker in Pennsylvania standing under a mile from where William Gabby lived in the 1760s.

What that marker records spans 1777 to 1789, overlapping William Gabby's years there.
