Last week, we covered the most common Cajun last names in Louisiana. That got us thinking, what would the least common Cajun last names be? If you have one of these last names, consider yourself pretty unique. It also means your family was one of the first Acadians in South Louisiana.

Acadian-cajun.com has some fantastic census information on Acadiana, dating all the back to 1604!

The last names listed below appeared on the 1604-1755 census during what is considered to be "The True Acadian Period". The names have pretty much disappeared because the family either moved, died off, or left no male sons to pass on the surname. Some of these names appeared in the original 1604 census, but never showed up again.

Below are the top 11 extremely rare or extinct Cajun last names in Acadiana.
