The Larkin-Ladd House at 180 Middle Street in Portsmouth, New Hampshire, is a three-story, masonry Federal-style residence with symmetrical facade, built for one of the city’s wealthiest merchants. Samuel Larkin (1773-1849) was born in Charlestown and moved to Portsmouth, marrying Ann Jaffrey Wentworth, a daughter of Col. Joshua Wentworth. During the War of 1812, Samuel Larkin made his fortune as an auctioneer, selling the contents of English ships captured by local privateers. It is believed that fourteen privateers and their crews worked out of Portsmouth Harbor and are said to have captured an estimated 419 British ships! With the profits from stolen goods from these British ships, Larkin purchased lots on Middle Street and began construction of this stately residence. He (and mostly his wife), had twenty-two children, although roughly half of them died before reaching adulthood. By the late 1820s, financial hardship fell on Larkin and he sold this property, moving into his house next door, which before this was his original residence and later rented to boarders. The Federal style mansion was later owned by Henry H. Ladd, a prosperous Portsmouth shipping merchant, who also served as President of New Hampshire Bank and Portsmouth Savings Bank. The Larkin-Ladd House is undoubtedly one of the finest Federal style residences in New England, and stands out for its entrance, flanked by Palladian windows and the slightly recessed elliptical surrounds at the first and second floor windows. Additionally, the historic stable, also from the 1810s, maintains much of its architectural integrity.
