Most of Alma Township was built recently: 5% of its homes predate 1940 and the median home dates from 1991. Below: maps from 1934 on and the census since 1900.
Alma was originally called "Rantoul", and under the latter name was laid out in 1854. The present name, adopted in 1855, commemorates the Battle of the Alma in the Crimean War. The village post office named "Grand Mound City" was changed to "Alma" in 1855 as well.
