Local historians map George Washington’s first public survey in Culpeper County

A local presenter and surveyor David Cubbage on Saturday described documentary and field work that they say locate the starting point of George Washington’s first recorded public survey in what is now Culpeper County. The presenters said Washington’s professional career began with a survey dated July 22, 1749, near Flat Run and Brandy Station.

The presenter, speaking to a museum audience, said the 1749 survey was “his first ever public work” and framed that date as the beginning of Washington’s public career. He told attendees that contemporary court records quoted in 19th‑century publications recorded a commission and oath making Washington the county surveyor, though the original mid‑18th‑century courthouse books were later lost.

David Cubbage, identified in the talk as a longtime local surveyor, described the team’s method: consulting published atlases and deed descriptions, plotting meets‑and‑bounds into modern CAD software and visiting the field. “When I got to the point of where I knew I had the goose, that’s where these points started showing up,” Cubbage said, describing eight physical points along Flat Run that he said match Washington’s original descriptions. He added that after plotting the geometry the polygon “comes out to be pretty close to 400 acres.”

The presenters traced how Washington’s family and patrons connected him to the area, noting ties to the Fairfax family and local figures such as Samuel Ball. They said Washington signed this first survey with his complete name and appended “surveyor of Culpeper County” — a treatment the presenters said Washington did not repeat on most later plats.

The talk documented archival locations for related material: the presenters said copies and related survey books are held in collections including the Library of Virginia in Richmond, the Library of Congress and Cornell University’s special collections. The presenters also described discovering an old colonial road and named chainmen from the Slaughter family who appear on the original survey notes, which they said strengthened the field match.

Cubbage and the presenter described technical limits and uncertainties in the reconstruction. They said some neighboring patent lines existing by 1749 would have shortened Washington’s fieldwork, and that translating compass-and‑chain measurements into modern coordinates requires approximations. The presenters estimated the fieldwork for such a survey could have taken roughly one to two weeks given the terrain and the use of a 66‑foot chain.

The museum said it plans to erect a marker on the property next year near Caracle Mills Road at a position the presenters identified as near the survey’s interior; the presenters described that as a public, interpretive marker rather than a legal boundary action. During a short question‑and‑answer session, an audience member asked about Washington’s pay; the presenter explained that the House of Burgesses set surveyor rates and that surveyors often received payment in land as well as cash.

The presenters emphasized that the reconstruction ties documentary references, surviving plats and visible field geometry together, and that the planned marker will be erected where the team believes the historic survey began. The museum will make copies of the presenters’ materials available after the event.
