Narrative: The first Holy Roman Emperor, who lived from 742-814, is known to English-speaking students of history as Charlemagne (French for ''Charles the Great.'')

Charlemagne was a powerful Germanic leader who synthesized a relatively ordered society out of the chaos that followed the fall of Rome. He not only united France, but much of central Europe. His widespread fame gave rise to many forms of his name, in many languages.

For example, in Latin he was referred to as Carolus Magnus, and in German as Karl der Grosse. Many of these forms remain popular names in their own right, or have formed the basis for other modern names.

Though this name appears on the 1990 U.S. Census lists, it is used by only a small percentage of the general population.

Narrative: Of all the feminine forms of Carl (and its equivalent Charles), the oldest is probably Carolina, which developed in Latin as a feminine form of Carolinus, itself an elaboration of Carolus.

Carolus Magnus was the Latin name of the first Holy Roman Emperor, a Germanic leader known in the English-speaking world as Charlemagne (French for ''Charles the Great''). He was crowned emperor in 800 A.D., after uniting much of central Europe and building a relatively stable society out of the chaos that followed the fall of Rome.

Charlemagne's widespread fame gave rise to many forms of his name in many languages. Each male form suggested a female equivalent, which in turn changed and developed, so that we see Carolina changed to Caroline, shortened to Carol, and so on.
