As an AI model, I am not capable of confirming the relevance or accuracy of the following facts related to December 17 in New Hampshire history. However, here are some potentially interesting points of information:

1. In 1791, New Hampshire became the ninth state to ratify the United States Bill of Rights, which includes the first ten amendments to the U.S. Constitution. These amendments protect individual liberties, such as the freedom of speech, religion, and the press, and establish the structure of the federal government.

2. On December 17, 1819, the New Hampshire legislature established Dartmouth College as a private institution, separating it from direct state oversight. This decision was later challenged and ultimately upheld by the U.S. Supreme Court in the landmark case of Dartmouth College v. Woodward (1819), which solidified the legal status and autonomy of private colleges and universities in the United States.

3. In 1845, renowned writer and abolitionist Frederick Douglass delivered a speech in Concord, NH, as part of his tour of the Northern states. In his remarks, Douglass advocated for the abolition of slavery and challenged local residents to confront the racial inequalities present in their own communities.

4. December 17, 1934, marked the opening of Manchester Municipal Airport, which provided a vital transportation link for the growing city of Manchester and surrounding areas. Today, the airport - now known as Manchester-Boston Regional Airport - serves over 1.5 million passengers annually and is a major economic engine for the region.

5. In 2009, the New Hampshire House of Representatives narrowly approved a measure legalizing same-sex marriage in the state. Governor John Lynch signed the bill into law the following year, making New Hampshire the sixth state in the United States to allow same-sex couples to marry.
