He built the Jennings depot on a divide peculiar to southwest Louisiana. This became the center of new development based on the railroad. The first settler was recorded as A. D. McFarlain, who came in 1881 from St. Mary Parish and opened a store. McFarlain also became the first rice grower, postmaster, brick maker, and builder in the community. Prospering with Jennings’ growth, McFarlain was considered one of the town’s prominent businessmen and civic leaders.The Jennings area attracted numerous wheat farmers from Iowa, Kansas, Nebraska and other Midwestern states. The new settlers of southwest Louisiana were referred to as "Yankees" by the natives, who were of Acadian French and African-American descent. They had settled along the waterways in the parish, which they had relied on for transportation before the railroad. They fished in the bayous. The Cajuns gave appreciable aid to the settlers in homesteading and homemaking. The people grew rice, cotton, sweet potatoes and corn.
