I don't know if this information will help at all, but at least it might be a possible connection or starting point for you. In the will of Sally A. Winn (She was formerly married to a Snead, then married Edmund Winn.) in Lunenburg Co., VA W.B. 13, p. 404, she names her son William Snead and Susan his wife, her son John Snead, and the balance of her estate (with no relationship given) to Alexander H. Snead, Hambleton Snead, and Greef A. Snead. The will is dated May 29, 1850, and proved in court on Aug. 12, 1850. These three Alexander, Hambleton, and Greef must be nephews, cousins, something. Although her second husband was very wealthy, he left his estate to his children by his first marriage. Sarah was not a wealthy woman in her own right. Her main property was about 45 acres of land which was left to her by her father Minor Wilkes. Surely, she would have been fond of these three boys to mention them in her will. Her son William was born ca. 1798, so he would have been a contemporary of your Hamilton. Hope this helps and good luck!
