Robert, the other brother of David and James, Sr., who settled at Fort Chiswell, Wythe county, Virginia, married in Ireland (or Scotland) Mary Craige, who bore him four sons and two daughters. The names of the sons were: Samuel, John, Robert and James; the daughters names being Margaret, who married a McGavock, and Nancy, who married a Crocket. After the death of Robert Graham’s first wife, he married a Miss Cowan, by whom he had three sons, David, Joseph and Calvin. From these have descended a large and influential family, who live in Wythe, Tazewell and adjoining counties.
Robert Graham accumulated a large landed property, which to this day is mostly in the hands of his descendants. As a remarkable coincidence, it wil1 be observed that the names of five of Robert Graham’s sons are the same as five of the sons of his brothers, David and James. In Robert’s family, we have Samuel, John, James, David and Joseph, while in James’ family there is John, who was killed by the Indians, Samuel, James and David; and David’s family, John and Joseph. These facts themselves, if  other evidence was wanting, prove beyond a doubt that they were brothers.
Samuel M. Graham, of Graham, Virginia, a great grandson of Robert Graham, who settled at Fort Chiswell, Virginia, about 1774. He claims that his great grandfather and the writer’s grandfather, James, who settled at Lowell about 1771, were brothers.
As a mark of military tack of this family, James was made a Colonel and his son, William, a Major of Monroe county, and Samuel, a son of Robert, was a major in Tazewell county. And as to their mathematical proclivities, the Grahams had a strong inclination. We can trace seven surveyors and four or five very prominent ones of the before named family.
