Before McDonoghville was established in 1815, the area was home to the Montplaisir plantation built by Jean-Charles de Pradel in 1750. De Pradel had acquired the land in 1737 from
Étienne Perier who'd received it as a grant from the
Company of the Indies upon becoming governor of Louisiana in 1726. In 1813, philanthropist
John McDonogh acquired the property and began subdividing the land to create McDonnoughville in 1815, the first subdivision in Jefferson Parish. McDonough leased and sold these properties to white laborers and free people of color, including people he'd previously held as slaves and hoped to prepare for returning to
Liberia as part of the
American Colonization Society migration project. For this reason, McDonoghville was also known informally as "Freetown". By the 1880s, McDonoghville had become a center for railroads with a roundhouse, railyards, and multiple spur lines. Railroad magnate
Jay Gould's holdings in the area were extensive enough for the area to be labeled "Gouldsboro" on an 1896 map. At the same time the area became a manufacturing hub and German immigrants settled in the town, followed in Irish and Italian immigrants in the late 19th and early 20th centuries. Reliable ferry service connecting the area with the East Bank facilitated the neighborhood's growth. == Sources ==
