From Greek Kynthia, an epithet applied to the goddess Artemis, who was supposed to have been born on Mount Kynthos on the island of Delos. The mountain name is of pre-Greek origin. Cynthia was later used by the Roman poet Propertius as the name of the woman to whom he addressed his love poetry. The English given name was not used in the Middle Ages, but dates from the classical revival of the 17th and 18th centuries.
English: occupational name for a roofer, from Old French co(u)vreur, an agent derivative of co(u)vrir ‘to cover’ (Latin cooperire). Roofing materials in the Middle Ages might be tiles (see Tyler), slates (see Slater), or thatch (see Thatcher), depending on the regional availability of suitable materials.
