Primary source documentation on the pre-1730 Natchez kinship and descent system is based on a relatively small number of French colonists who recorded information about Natchez social life between about 1700 and 1730. Fragmentary and ambiguous, the French accounts are the only historic accounts of Natchez society before 1730. Natchez oral traditions have also been studied. The first modern ethnographic study was done by John R. Swanton in 1911. Swanton's interpretations and conclusions are still generally accepted and widely cited. Later researchers have addressed various problems with Swanton's interpretation. Some researchers have proposed modifications of Swanton's model, while others have rejected most of it.
