Most of Chataignier was built recently: 3% of its homes predate 1940 and the median home dates from 1974. Below: maps from 1922 on and the census since 1980.
The name Chataignier is French and means "chinquapin," a small chestnut. Chinquapins (Castanea pumila) grew abundantly in the surrounding prairie until the chestnut blight wiped them out. They are now non-existent in the Chataignier community.
