Two generations of enslavers lived at the Moffatt-Ladd house during the American Revolution: John Moffat, his daughter Katharine, and his son-in-law, William Whipple. In November of 1779, Prince Whipple and Windsor Moffatt, two men enslaved at the Moffatt-Ladd House, joined 18 other men to petition the legislature of the state of New Hampshire for their freedom. Their petition was unsuccessful.
Visitors to the Moffatt-Ladd House learn how Prince and Windsor may have become familiar with the language of independence while enslaved in the Moffatt-Ladd household, and discover the legacy of slavery in New Hampshire.
