A gazetteer is a list and description of places. It can be used to locate the places where your family lived. Gazetteers describe towns and villages, sizes of population, rivers and mountains, and other geographical features. They usually include only the names of places that existed at the time the gazetteer was published. The place names are generally listed in alphabetical order, similar to a dictionary.
Two helpful guides to Louisiana place-names are:
- Gibson, Dennis A., ed. Index to Louisiana Place Names Mentioned in the War of the Rebellion: A Compilation of the Official Records of the Union and Confederate Armies. Lafayette, Louisiana: University of Southwestern Louisiana, 1975. FHL book 976.3 E5i
- Hansen, Harry, ed. Louisiana: A Guide to the State. New York, NY: Hastings House, 1971. FHL book 976.3 E6h. This is a revised edition of a 1941 WPA publication.
How did your ancestor find the correct destination out West? Quite possibly they had a copy of Brown's book:
