This collection contains materials from Simeon Valery Martin, Louis E. Labaire, Robert Martin, and James J. Martin, but mainly Robert Martin. There are also copy books of business letters written by Robert Martin as both a lawyer and as a businessman. Many of the pages are illegible due to fading and ink bleed-through. The first 4 volumes are mainly in French and there are scattered French documents in others. The volumes are roughly arranged chronologically.
