This collection consists of fifteen letters by Warren Hubert Moïse, eleven to his nephew Edwin Warren Moïse and four to Edwin's wife, Marion Cobb Gerdine Moïse. The letters discuss the careers of Warren Hubert's father, Edwin Warren Moïse, a prominent attorney, legislator, and judge in Louisiana, and his uncle, the painter Theodore Sidney Moïse. Warren Hubert details the Moïse family's financial struggles after the Civil War and provides genealogical information about the extended Moïse family as well as the family of his mother, Louise Hubert, Edwin Warren's second wife, and the family of Matilda Jane Vaughn, Theodore Sidney's second wife. The collection also includes two letters to his nephew Edwin Warren Moïse from the Metropolitan Museum of Art offering advice on care of a portrait of his grandfather, Edwin Warren Moïse, painted by Theodore Sidney Moïse, as well as a series of photographs of Warren Hubert Moïse and friends originally enclosed in a letter to Edwin Warren Moïse. Part of the Jewish Heritage Collection, The Warren Hubert Moïse Letters were donated to the College of Charleston's Addlestone Library by Marion Gerdine Moïse Bierwirth in 2009.
