Hamilton was made Sheriff of Linlithgow in 1600, received large grants of lands in Scotland and Ireland, was created in 1603 Baron Abercorn, and on 10 July 1606 was rewarded for his services in the matter of the union by being made Earl of Abercorn and Lord Paisley, Hamilton, Mountcastell and Kilpatrick. He married Marion, daughter of Thomas Boyd, 5th Lord Boyd, and left nine children:

James Hamilton, 2nd Earl of Abercorn (c. 1604 – c. 1670), created Lord Hamilton, Baron of Strabane in the Peerage of Ireland in his father's lifetime.
Sir William Hamilton, 1st Baronet (c. 1605–1680)
Claud Hamilton, 2nd Baron Hamilton of Strabane (c. 1606–1638)

He died on 23 March 1618. His heirs, Earls of Abercorn, heads of the Hamilton family, became Marquesses of Abercorn in 1790, and Dukes of Abercorn in 1868; the 2nd Duke of Abercorn (b. 1838) being a prominent Unionist politician and chairman of the British South Africa Company. The present Dukes are descended from his fourth son, Sir George, the issue of the three elder being extinct.
Connection to the Hamilton family is not proven in my tree but is a result of merging on Geni.
