Col. Hamilton's executry RH15/119/92-110 Including papers relating to Janet Hamilton (Dundas), his widow, and William Dundas, M.P., her brother and executor.
These papers appear to have been collected together for William Dundas, M.P., as executor of his sister, Janet, widow of Colonel John Hamilton of Pencaitland, probably to provide evidence in an action against the heirs of entail of the estates of Pencaitland and Winton for payment of debts affecting Hamilton's estates and succession. They were probably brought into the Register House while Dundas was Lord Clerk Register (1821-45).
Colonel Hamilton's mother, Mary Hamilton, suceeded to her father's estates of Barncluith (Lanarkshire), Dechmont (West Lothian) and Pencaitland and Saltcoats (East Lothian) in 1758 and to the estates of Belhaven, Biel and Presmennan (East Lothian) in 1777, as heir of entail of the 5th Lord Belhaven. In 1779 she purchased Winton at the judicial sale of the estates of the York Buildings Company. By her marriage to William Hamilton Nisbet of Dirleton (1747) she had two sons. The elder, William Hamilton Nisbet, succeeded to his father's estates, but under the marriage contract her own estates were entailed to the younger son, John, who subsequently assumed the name of Hamilton.
John Hamilton was infeft in Pencaitland on his mother's resignation in 1773 and succeeded to her other estates on her death in 1797. Having served in the Scots Greys, he became colonel of the East and West Lothian Fencible Cavalry. In 1801 he was appointed Receiver General of Land Rents and Taxes for Scotland. On his death in 1804; Pencaitland passed to his sister, Mary Hamilton Campbell, wife of Walter Campbell of Shawfield, and Winton to her son, William Hamilton Campbell. His widow, Janet, daughter of Robert Dundas of Arniston, Lord President of the Court of Session, died in 1810. Other papers relating to the same families and estates will be found in the Biel (GD.6) and Ogilvy of Inverquharity (GD205) Muniments.
