Charlotte is the French feminine form of Charles, itself from a Germanic root often given as "free man" or "strength." Over time the diminutive form softened the association toward something more delicate, and the name is now commonly linked with a blend of gentleness and quiet resolve rather than raw power.
When the Sun in the daytime, and the Moon in the night, in the beginning of any sickness, is impedited, the person is to be feared. - William Lilly (1602.-1681.)
