=== Finding Place Names in the Family History Library Catalog ===
Place names in the Family History Library Catalog are listed under their modern names and current municipalities and states as they existed in 1993. To find the municipality that a town is filed under in the Family History Library Catalog, you can do a <br>"Place Search" in the catalog at [http://www.FamilySearch.org www.FamilySearch.org]. Because of the many changes in place names, the Family History Library uses one gazetteer as the standard guide for listing places in the Family History Library Catalog. Regardless of the names a place may have had at various times, all Brazilian places are listed in the Family History Library Catalog as they are listed in:
''Cadastro de Municípios (Survey of Municipalities''). Rio de Janeiro: Fundação Instituto Brasileiro de Geografia e Estatística, 1993. (FHL book 981 E5c)
=== Modern Place Names ===
For some research purposes such as correspondence it is useful to learn modern jurisdictions for the area where your ancestor lived. This may also be helpful when finding the ancestral town on modern maps. In addition to the above gazetteer, the following modern gazetteers may be found at large libraries and archives and in the Family History Library:
=== Historical Place Names ===
Because names and boundaries of some places have changed or no longer exist, you may need to use gazetteers, maps, or local history sources that describe places as they were known earlier. For example, there are four places in Brazil with the name João Pessoa. One of these towns was known as Porto, in the state of Piauí, prior to 1930. Between 1930 and 1944 it was known as Marruás, but it is now known as João Pessoa. A gazetteer will help you sort this information.
