From source materials available in some of the major Spanish archives, the author has abstracted from original census documents genealogical data about individuals and families who settled in the French territories of Louisiana and the Floridas after they came under Spanish rule in 1766 (the areas settled correspond to the present- day states of Delaware, Florida, Alabama, Mississippi, Louisiana, and Missouri in the US and to Belize, formerly British Honduras, in Central America). The time period of the tabulated census data is ca. 1781-1797.
