Molina is a Spanish occupational surname. Molina is Latin for 'mill' and is derived from another Latin word, mola ('millstone'). The surname originated from the early Middle Ages, referring to a person who operates a mill or a millstone.[1] Other Spanish surnames, like Molinero (literally: 'miller'), have also originated in the work and management of a mill. Spanish municipalities like Molina de Segura (Murcia) or Molina de Aragón (Castilla-La Mancha) still nowadays include millstones or mill blades in their respective coats of arms (cf. coat of arms of Molina de Segura and Coats of arms of Molina de Aragón).
A bloodline of Molinas, in the Christian Kingdom of Castile, originated from ennoblement when Manrique Pérez de Lara, of the House of Lara, in April 1154 issued a fuero to the town of Molina, nowadays called Molina de Aragón.[2]
