The present-day community of Lawrenceton is about 15 miles west of Ste. Genevieve. It is unincorporated, but in its heyday, it had a post office between 1867 and 1941. The initial town, Punjaub, officially changed to Lawrenceton in 1877. So how did an Ozark border community receive the name of a region in India, then later become Lawrenceton?
