I am trying to locate some land belonging to an ancestor of mine.
property description notes that this ancestor's property was a part of the
original survey for Lord Fairfax. I also found some information that Lord
Fairfax's survey was "proprietary."
The knowledge that the original survey was for Lord Fairfax only tells you
that the land was between the Rappahannock and the Potomac Rivers, which
pins it down to something like eight million acres spread over more than a
dozen modern counties. That is a start but I would look for some other clues.
