fem. proper name, from Spanish Maria de los Dolores, literally "Mary of the Sorrows," from plural of dolor, from Latin dolor "pain, sorrow," perhaps from PIE root *delh- "to chop" "under the assumption than 'pain' was expressed by the feeling of 'being torn apart'" [de Vaan].
Lolita
fem. proper name, diminutive of Lola (thus a double diminutive). Title and character name in the 1958 novel by Vladimir Nabokov (1899-1977) "about a precocious schoolgirl seduced by a middle-aged man" [OED]; hence figurative use (by 1960) "to designate people and situations resembling those in the book."
