Van wie was Lady Mary Butler?

Sir George Hamilton, 1st Baronet of Donalong and Nenagh (c. 1608 – 1679), was born in Scotland, but inherited land in Ireland. Despite being Catholic, he served his Protestant brother-in-law, the 1st Duke of Ormond, lord lieutenant of Ireland, in diplomatic missions during the Confederate Wars and as receiver-general of the royalists. He also defended Nenagh Castle against the Parliamentarians during the Cromwellian conquest of Ireland. Hamilton was father of Anthony, author of the Mémoires du Comte de Grammont, of Richard, Jacobite general, and of Elizabeth, "la belle Hamilton".
