Upon returning to Virginia, Stuart established a medical practice in
Alexandria. He lived and farmed mostly outside of Alexandria in
Fairfax County, Virginia. His first farm was at the
Abingdon plantation, which was within the area that Virginia ceded to the federal government in 1791 to help create the future
District of Columbia in accordance with an amendment to the federal
Residence Act. Partially located on the grounds of
Ronald Reagan Washington National Airport, the Abingdon plantation's site is now within
Arlington County, Virginia. Stuart and James Wright purchased a lot in the town of Alexandria in 1783, during the same year Stuart married
Eleanor Calvert Custis, the widow of
John Parke Custis. Stuart used slaves when farming. Several letters between the former president and Stuart, some of whose farming activities benefitted his stepchildren, as the residual beneficiaries of the
dower slaves, discussed the gradual abolition of slavery, as well as white landowners who harassed free Black landowners, knowing that Virginia's law against allowing Blacks to testify meant that illegal actions could have no negative consequences. In the 1787 tax census Stuart owned 13 adult and nine child slaves in Fairfax County, while his father owned 16 adult and 16 child slaves in King George County. His minister father retired in 1796 and died in 1798. His stepson
George Washington Parke Custis later criticized the former president's testamentary manumission of his slaves, helped the widower Stuart advertise the sale of slaves in Alexandria in 1812, and at his own death freed many slaves. Fairfax County voters elected and thrice re-elected Stuart as one of their representatives to the
Virginia House of Delegates, and he served in that part-time position from 1785 until 1789. Voters in the Prince William District chose Stuart as an elector for the
1788-1789 Presidential election. That District consisted of the counties of Fairfax, Fauquier, Loudoun and Prince William, which cover the area south and west of present day Washington D.C. Each of the ten Virginia electors cast one of their two votes for George Washington. There is no record of how the individuals of the Virginia delegation voted for Vice-President, but five of those electors cast their other vote for
John Adams; three cast theirs for
George Clinton; one cast his for
John Hancock; and one cast his for
John Jay. Stuart ended his state legislative career by representing Fairfax County in the
Virginia convention of 1788 that considered the
ratification of the United States Constitution. Stuart served alongside Alexandria lawyer
Charles Simms, also a staunch Federalist and multi-term Fairfax County representative in the House of Delegates;
George Mason had often represented Fairfax County in the House of Delegates and also served in the
Constitutional Convention in
Philadelphia, where the
U.S. Constitution was drafted. He vocally opposed ratification, leading Fairfax County voters to refuse to elect him to the Ratification Convention. Thus Mason instead represented Stafford County at the convention, where he and
Patrick Henry led the anti-Ratification forces. Westmoreland County southeast of Fairfax County also elected federalist or ratification advocates:
Henry Lee III (Light-Horse Harry Lee) and General Washington's nephew (and eventual heir),
Bushrod Washington. In the near final vote after extensive debate, the convention considered the following resolution:
Resolved, That previous to the ratification of the new Constitution of government recommended by the late Federal Convention, a declaration of rights asserting and securing from encroachment the great principle of civil and religious liberty and the unalienable rights of the people, together with amendments to the most exceptional parts of the said Constitution, ought to be referred by this Convention to the other States in the American Confederation for their consideration. Federalist or ratification forces led by
James Madison,
John Marshall and
Edmund Randolph, defeated the Mason/Henry resolution, 88—80. In their first year, Stuart and the other commissioners named the capital the "City of Washington" in "The Territory of Columbia". On April 15, 1791, he and anothor commissioner,
Daniel Carroll, attended a ceremony at which the first boundary stone (the south cornerstone) for the Territory of Columbia (the future District of Columbia) was placed at
Jones Point, the tip of a
cape immediately north of the confluence of
Hunting Creek and the
Potomac River. Stuart was also a founding trustee of the towns of
Centreville and Providence (now
Fairfax City), and of the Centreville Academy in 1808. ==Family==
