Legend says an early traveler, unable to buy a single loaf of bread there, facetiously called the place "short of bread town", which translates to Paincourtville.
The first permanent settlements in this region were made by the French and Spanish (including Isleños), circa the mid-18th century along Bayou Lafourche, between the present towns of Donaldsonville and Napoleonville. From 1755 to 1764, the population was increased by the immigration of the exiled Acadians who emigrated to the area, clearing the land and building homes. Many of their descendants remain in the parish today.
On a plot donated by Elizabeth Dugas, St. Elizabeth's Church was built in 1840. Parishioners promptly rebuilt their church after a fire in 1854. In 1903 a third structure, still in use, was completed. Nearby on a special steel scaffolding is the church bell, too large for either of the church's two towers. It was brought from France.
