Jane Pierce disliked Hillsborough as well, and in 1838, the Pierces relocated to the state capital, Concord, New Hampshire.[30] They had three sons, all of whom died in childhood. Franklin Jr. (February 2–5, 1836) died in infancy, while Frank Robert (August 27, 1839 – November 14, 1843) died at the age of four from epidemic typhus. Benjamin (April 13, 1841 – January 6, 1853) died at the age of 11 in a train accident.[31]

Congressional career
U.S. House of Representatives
Pierce departed in November 1833 for Washington, D.C., where the Twenty-third United States Congress convened its regular session on December 2. Jackson's second term was under way, and the House of Representatives had a strong Democratic majority, whose primary focus was to prevent the Second Bank of the United States from being rechartered. The Democrats, including Pierce, defeated proposals supported by the newly formed Whig Party, and the bank's charter expired. Pierce broke from his party on occasion, opposing Democratic bills to fund internal improvements with federal money. He saw both the bank and infrastructure spending as unconstitutional, with internal improvements the responsibility of the states.
