5. On this day ... June 24, 1803, New Hampshire's ex post facto signer of the Declaration of Independence, Matthew Thornton, died at 89-years old. One of the Granite State's delegates to the second Continental Congress, Thornton was born in Ireland, moved to the northern part of the Massachusetts territory (now Maine), was educated in Worcester, MA, and then opened a medical practice in Londonderry – where he later purchased significant land holdings - in 1740. According to History.com:

In 1775, Thornton became the first president of the Provincial Assembly and chairman of the Committee of Safety, as relations between Britain and its American colonies deteriorated. Thornton penned the document that would serve as New Hampshire's first state constitution. In 1776, he was elected to the second Continental Congress. Because he did not arrive in Philadelphia until September, he missed the debates and initial approval of the Declaration of Independence, but later added his signature to the document.

Upon his return to New Hampshire, Thornton became a high judge and colonel in the militia. In 1779, he moved to Exeter, where he served the new state in the Assembly and Senate, before retiring to a farm in Merrimack 10 years later.
