Cleason is a unique and uncommon given name of American origin. It is believed to have derived from an Old French personal (or possibly place) name, Clayson, which is thought to mean 'clay town'. Cleason has not been widely popular throughout history but it does hold historical significance as it was occasionally used in the United States during the late 19th and early 20th centuries. Today, however, it remains quite rare, with only a small number of people worldwide bearing this distinctive name.
"Cleason seems to have experienced a surge in popularity in the early 2000s and again around 2013."
