This collection initially consisted of a portrait and a land grant. Azema Demarais, the granddaughter of Louis George Demaret and raised at the old family home on the Bayou Teche, is the subject of the portrait that is currently displayed in the Jefferson Caffery Reading Room. There is a little damage on the left edge facing the portrait, which according to oral family history, was inflicted by a Union soldier. The 1786 land grant is written in Spanish. An addition donated in 2023 contains photographs of descendants, birth and marriage records, correspondence (including a copy of a 1788 letter), and various genealogy materials relating to the Demarais and Navarro families.
