Name origin
Dolores is an English, German, and Spanish feminine name. It is derived literally from the Spanish word dolor meaning "sorrow, grief, pain", plural dolores "sorrows". In Spanish, where the name originated and is more prevalent, it is short for La Virgen María de los Dolores, "Virgin Mary of Sorrows", and is often shortened to the more colloquial forms Lola, Lolita or Loli.
