Caroll is an unusual yet charming name of English origin, derived from the Middle English 'carole,' which referred to a type of round dance and song popular during medieval times. The name gained prominence through its association with Carroll Shelby, the renowned American automotive designer and racing driver.
"The name Caroll experienced significant popularity between the late 1930s and early 1950s, with a peak of 65 births in 1946, but has since become quite rare, with fewer than 10 births per year since the 1970s."
