Most of St. Francis was built recently: 7% of its homes predate 1940 and the median home dates from 1964. Below: maps from 1940 on and the census since 1890.
The St. Francis area was settled in the 1840s, with the early residents forming the Chalk Bluff community just northwest of the present city. The Battle of Chalk Bluff was fought here in May 1863, during the Civil War. In 1882, the St. Louis Southwestern Railway ("Cotton Belt") was constructed through the area, and the Chalk Bluff community gradually shifted southeastward to a location along the railroad tracks. This new community was named "St. Francis" after the adjacent river (the river itself was named after Francis of Assisi).
