Sir George Hamilton, 1st Baronet, of Donalong
Sir George Hamilton, 1st Baronet (c. 1607–1679), an Irish baronet, was one of the proprietors of the silver mines of Knockaunderrig before the English Civil War.
The fourth son of James Hamilton, 1st Earl of Abercorn and Marion Boyd, Hamilton's early advancement was hindered by his Catholicism, but he was appointed a colonel of foot in 1649, and upheld the Royalist cause in Ireland. He was the commander at Nenagh when Ireton arrived to besiege it for the Parliamentarians in October 1650. Initially defiant, he surrendered to Ireton when the latter threatened to breach the walls with artillery. Hamilton's Irish lands were confiscated and he went into exile in Paris. Upon the Restoration, he was high in favor with Charles II and was created a baronet in 1660.
