Lockport, founded in 1835, traces its history to Jacques Lamotte, who in 1790 owned a large tract of land along Bayou Lafourche. Lemotte sold a portion of the tract to Messrs. Mercier and Marcantel in 1814. In 1823 William Field purchased a parcel of the land and later donated 5 arpents of it on both banks of Bayou Lafourche to Barataria and Lafourche Canal Company. As part of the transaction, the company agreed to build a canal, which would link Bayou Terrebonne to New Orleans. Allou D'Hemecourt surveyed the area in 1835. His map bears the name Longueville. Eventually, the village's name would become Lockport.
