Decatur, of French origin, is an unusual yet distinguished given name derived from 'd'Ecatre,' which translates to 'from Ecatre.' This name was popularized by Commodore Stephen Decatur, a hero of the First Barbary War in the early 19th century, and has since been associated with military valor and patriotism.
"From 1916 to 2017, the name Decatur has had a fluctuating popularity in terms of births, with periods of consistency around five births per year and peaks at seven in 1945 and 2008. Overall, there have been 54 babies named Decatur during this time."
