Maria Carter Syphax died in 1886 in the Arlington area of Virginia, after a long life spanning enslavement, freedom, and the struggle to secure her family's property. In her later years she remained associated with the land at Arlington that had been set aside for her household. Wartime confiscation had placed that property in jeopardy, and her son William obtained congressional recognition of her title in 1866. These events establish the setting of her old age, but they do not identify a terminal illness or prove the circumstances of her last days. The available biography gives no dependable medical cause, treatment history, or precise death day. Her husband Charles and their descendants belong to the same family story, yet accounts of their deaths should not be substituted for hers. Her final chapter is therefore a documented death year and family location, with the personal medical details acknowledged as missing.
