Built in ca. 1745, the Gregg-Nichols House in Loudoun County reflects the broad patterns of Quaker settlement into the frontier of Virginia in the 18th century, when Quakers from Pennsylvania and Delaware bought land grants in Virginia’s northern region to build houses and farm the land. Owned by the Gregg and Nichols families for over a century, the dwelling serves as an excellent example of a Quaker vernacular patent house that adheres to an 18th-century Virginia law requiring land grantees to construct a house with the dimensions of 16’ x 20’ and to plant and farm an acre of land within three years of purchase.
