The Carrs were a prominent family in Albemarle County who had close associations with the Jeffersons. Dabney Carr (1743-1773) was a close friend of Thomas Jefferson, and married Jefferson's sister Martha on 20 July 1765. After Dabney Carr's early death in 1773, Thomas Jefferson oversaw much of his sons' education, and Martha and her six children spent a great deal of time at Monticello.
1793 February 27. (Martha Jefferson Randolph to Jefferson). "Poor Jenny Cary has Lost her husband and her sister Lucy is married to a Mr. Teril with whom she goes to Kentucke this spring so that Aunt Carr will have only one of her children with her it being the intention of Sam to settle imediately upon his own Land in this neighbourhood."
1798 March 20. (Mary Jefferson Eppes to Jefferson). "Aunt Carr is return'd from Celies in good health and is at present with Aunt Bolling, who is in tolerable health, the former will be here soon, where she will stay I expect and go up with US." (FAH)

1799 April 13. (Jefferson to Mary Jefferson Eppes). "I suppose you have heard before that Peter Carr had a son and Sam a daughter. Sam and his wife are daily expected from Maryland." 
1801 June 19. (Martha Jefferson Randolph to Jefferson). 'Your stockings are at last disposed of, but not to my satisfaction because I am sure they will not be so to yours. Aunt Carr after many ineffectual efforts to put them put acceded at last to the united and importunate entreaties of Mrs. Randolph and Mrs. Lilburn Lewis to let them knit them for you...."
1802 March. 3. (Jefferson to Mary Jefferson Eppes). Suggestions on route from Bermuda Hundred to Washington, "and crossing Patomac at Boyd's hole you would come up by Sam Carr's to this place."
1802 July 1. (Jefferson to Mary Jefferson Eppes). "Dabney Carr was married on Monday (28th. ) and set out yesterday (30th.) with his new wife for Albemarle where he will join his mother now keeping house at Dunlora, till he can fix himself in Charlottesville which will be soon. Sam Carr returns decidedly to live at Dunlora. The marriage of the other sister to Dabney seems to have effected this. Peter and his wife are expected here daily on their way to Baltimore."
1803 April 25. (Jefferson to Mary Jefferson Eppes). "Mr. and Mrs. P. Carr staid with me 5. or 6. days on their way to Baltimore. I think they propose to return in June. Nelly Carr continues in ill health. I believe they expect about the same time to get back to Dunlora."
1805 July 11. (Martha Jefferson Randolph to Jefferson). "The marriage [between Virginia Randolph and Wilson J. Caryl will take place at Monticello early in August entirely private except the old Gentleman and Lady and Aunt Carr. There is however a possibility of it's being delayed by the illness of Mrs. Cary's youngest daughter whose situation is extremely critical and will be lingering, which ever way it terminates. I am afraid however the phisicians will expedite the business; a feeble constitution reduced as low as she is, is not apt to linger in their hands.... We have this moment heard of the death of S. Carr's eldest daughter, the little girl my Aunt had with her at Monticello."
1807 March 20. (Martha Jefferson Randolph to Jefferson). "To give you a still better idea of the labours which await you, Mr. Carr told me of their putting 9 horses to one waggon..." <Ibid, 303.</ref>

When she was carried in the house she was horribly bruised but none of her bones broken."
