Correspondence among miscellaneous family members, ranging from an 1821 letter written by Carlos Colby's mother, to a 1934 letter by Ida Colby, Carlos Colby's daughter-in-law. Several letters contain genealogical information. Family writings include a detailed genealogical report and a copy of a fragment of a memoir by James Rowe. Miscellaneous material includes a picture of the Colby family crest and a fragile copy of the Vicksburg Daily Citizen of July 2, 1863, the last issue of that paper to be printed on wallpaper. Also includes a group of photographs of Carlos Colby and his family.
