Caroll, of Germanic origin, is a unique and uncommon name derived from the Old German words 'kar' meaning 'strong' and 'hilt' meaning 'helmet'. It was originally a surname given to someone who worked as a smith or maker of helmets. Over time, it has evolved into a unisex given name, adding a distinctive touch to those who bear it.
"Caroll saw its peak popularity during the late 1920s to early 1930s with over 20 births per year from 1928 to 1932. However, it declined thereafter, dropping below 10 births per year in the mid-1960s."
