The Montgomery collection consists of 3 letters and 1 poem related to Richard Montgomery and his wife, Janet Livingston. Three of the items are addressed to British Army officer Perkins Magra.
In the first letter, dated from Dublin on November 27, , Montgomery complained about a woman whom he claimed had infected him with a venereal disease. In a letter to Magra dated 1774, Montgomery discussed his decision to live in the countryside, and shared his conviction that he would be killed "by a pistol." Montgomery's final letter concerns events in Boston, the widespread political influence of the Second Continental Congress, and George Washington and Charles Lee (July 2, 1775). The collection also contains a narrative poem that Janet Livingston Montgomery wrote for Magra on May 25, 1775, with a brief prose postscript dated June 1, 1775. Montgomery congratulated Magra on his marriage and commented on the Battle of Bunker Hill, her husband's appointment to the provincial congress, and the possibility of war.
