This collection consists of 100+ letters written between the years of 1863–1868, and is accompanied by a book entitled, The Heizer Family: American Pioneers by James Harion Heizer c.1861-1868. The majority of the letters are authored by James Francis (Frank) Heizer (1841-1930), a private in the Confederate army, whose letters are mostly addressed to his love interest and eventual fiance, Pheobe Ann McCormick (1845-1906). This collection also includes a few of Pheobe's letters to Frank, though many of her letters were burned after being answered, as per a request by Pheobe in an attempt to conceal their relationship status until after the war. The letters include a variety of information about the war and Heizer’s movements throughout the state, along with his wishes for leave and travel plans. Along with these wartime details, the letters include a good deal of conversation involving the blossoming friendship between Frank and Pheobe, and eventually their romantic relationship. This period includes letters in which their engagement is made and then broken, and is followed by letters that include much sarcasm and veiled insults towards one another. After about a year, the pair had reconnected and had re-established their engagement, eventually marrying and having 9 children together.
