Name invented by Jonathan Swift (1667–1745) for his friend Esther Vanhomrigh. It seems to have been derived from the first syllable of her (Dutch) surname, with the addition of the suffix -essa (perhaps influenced by the first syllable of her given name). The name became fairly popular in the 20th century, being borne for example by the actress Vanessa Redgrave (b. 1937).
Spanish (Mármol): from mármol ‘marble’; perhaps a topographic name for someone who lived in an area of marble, a habitational name from either of two places called El Mármol (in Cádiz and Jaén provinces), a metonymic occupational name for a stonemason or quarryman, or a nickname for a cold, unresponsive person.
