[5] Jefferson left a sketch and specific instructions for the size and material of the monument he wished to be erected over his grave, and the inscription he would prefer.
"Could the dead," Jefferson had written on the back of a partially mutilated envelope, "feel any interest in monuments or remembrances of them," he would prefer "on the grave a plain die or cube three feet without any mouldings, surmounted by an obelisk of six feet height, each a single stone: on the faces of the obelisk the following inscription and not a word more – On the Die By these as testimonials I had lived and desire most to be remembered."
The obelisk was fabricated by John M. Perry and James Dinsmore, who had earlier helped Jefferson as carpenters and builders of Monticello, and placed over his grave with a white marble slab around the base.
[6] The inscription bears these words: This Graveyard had its beginning in an agreement between two young men, Thomas Jefferson and Dabney Carr, who were schoolmates and friends.
A buffet supper is also served featuring typical dishes of the colonial era, with period music provided by a strolling minstrel.
Following the ceremony at the Monticello Graveyard, the members of the family repair to a suitable place in Charlottesville, Virginia for a luncheon and business meeting.
[11] By 1950, The Monticello Association had outgrown the dining room, and from 1950 to 1982, the family was served a buffet luncheon at the Keswick Hunt Club.
[13] In recent years the luncheon and business meeting have been held at Alumni Hall at the University of Virginia, at the Visitor's Center at Monticello, or some other suitable place in Charlottesville.
On the whole, however, considering the diversity of age, geography, personality, and philosophy represented in the family, the prevalence of good humor and search for consensus generally mark the business sessions.
The study team noted that the body of historical evidence made it most likely that Thomas Jefferson was the father of Eston and all of Hemings' children.
[14] Together with existing historical evidence, the DNA study convinced former skeptics and Jefferson biographers, such as Joseph Ellis and Andrew Burstein, that the president had a long relationship with Hemings and likely fathered all her children.
[14] The DNA study was done after Annette Gordon-Reed published her analysis of the historiography in 1997, in which she showed how historians had shown bias and overlooked evidence.
The Thomas Jefferson Foundation, which operates Monticello, has incorporated the material into its training for guides, published new studies related to this conclusion, and expanded its research agenda.
[18] In 2003 Susan Stein, curator of Monticello, said, "more than 90 percent of professional historians who've looked at this are persuaded that Jefferson and Hemings had a sustained relationship.
[20] The president of the association did not allow a vote on whether to include the descendants as honorary members, saying this status was reserved for persons at the University of Virginia and the Thomas Jefferson Foundation.
The association's decision precluded Hemings' descendants from burial at the privately owned Jefferson family cemetery at Monticello, a privilege reserved to members.
[20] In the fall of 2001, the National Genealogical Society Quarterly reported that the "weight of historical evidence" and the DNA study were sufficient to conclude that Jefferson had a long relationship with Hemings and fathered all her children.
They strongly criticized a report issued that year by the newly formed Thomas Jefferson Heritage Society (TJHS); they said it failed to follow best practices in historical and genealogical analysis.
Leary, a certified genealogist, concluded: "the chain of evidence securely fastens Sally Hemings's children to their father, Thomas Jefferson.
"[22] In a 2002 lecture at the Library of Congress, Leary said: "[M]uch of the evidence marshaled against the Hemings-Jefferson relationship has proved to be flawed by reason of bias, inaccuracy or inconsistent reporting.
At that reunion, John Works Sr., a Monticello Association member, said he hoped other Wayles-Jefferson descendants would eventually accept the Hemingses.
[26] The private Monticello Association denied the crowd's access to the cemetery that weekend, claiming a concern for the grass.
[26] In 2010 the international peace-making organization "Search for Common Ground" honored three Jefferson descendants for "their work to bridge the divide within their family and heal the legacy of slavery.
