Last name: Castello. This interesting name is of early medieval English topographical origin, and is derived from the Anglo-Norman French castel, castle, fortified building or set of buildings, especially the residence of a feudal lord.

The Spanish equivalent rank of coronel was used by the Spanish tercios in the 16th and 17th centuries. Gonzalo FernÃ¡ndez de CÃ³rdoba, nicknamed 'the Great Captain', divided his armies in 'coronelÃ­as' or colonelcies, each led by a coronel (colonel). However, the Spanish word probably derives from a different origin, in that it appears to designate an officer of the crown (corona, thus the rank coronel), rather than an officer of the column (columna, which would give the word columnal). This makes the Spanish word coronel probably cognate with the English word coroner. As the office of colonel became an established practice, the colonel became the senior captain in a group of companies that were all sworn to observe his personal authority â to be ruled or regimented by him.
