Putnam County, Missouri
Putnam County was organized on February 28, 1845, carved from the rolling tallgrass prairies and high ridges of Missouri’s far northern border. Early settlement grew around small farming communities, timbered creek valleys, and the overland routes that connected Missouri with southern Iowa. The county seat shifted several times in its early years before settling permanently at Unionville in 1853.
Throughout the mid‑1800s, pioneers from Kentucky, Tennessee, Ohio, and Pennsylvania established homesteads, schools, and churches across the prairie townships. The arrival of the railroad in the 1870s strengthened local trade and helped small towns flourish. Though the population peaked around the turn of the century, Putnam County has remained a region of close‑knit rural communities, preserved records, and deep family roots along the Missouri–Iowa line.
