Drennon is an uncommon yet distinctive given name of American origin. It is thought to be derived from Old German elements 'treno' meaning 'proud' and 'mann' signifying 'man'. Thus, Drennon could loosely translate to 'proud man'. The name has gained some popularity in the United States but remains relatively unique.
"The name Drennon has seen two spikes in popularity, with five babies named Drennon born each year in 1938 and again in 2019."
