According to my information, Thibodaux isn't exactly a small village - it is a town of 14,000 people, the seat of Lafourche Parish, Louisiana.

After searching the Internet diligently for evidence of a place called Fontaineau and trying various spellings including Fontaineaux, Fountaineau, Fountaineaux, Fontainbleau, Fontainebleau, Fountainbleau, Fountainebleau, I have come to the conclusion that the correct spelling must be FONTENOT, which is an unincorporated place 4 miles south of Kinder, Louisiana, right on the border between Allen Parish and Jefferson Davis Parish. Because it is unincorporated, no population figures are available, but "small village" is probably accurate.

That would put Thibodaux and Fontenot about 120 miles apart, as the crow flies. You likely would pass through Thibodaux en route from Baton Rouge to Grand Isle, but you wouldn't go near Fontenot, so I'm at a loss to explain what you saw, Fortunato. (And, by the way, didn't you mean "Laissez les bon temps roulez!"?)

I found Fontenot by using the USGS Geographic Names Information System at http://www-nmd.usgs.gov/www/gnis/gnisform.html

Fontenot is also a fairly common surname in that area.
